Halo Infinite LASO is FINALLY done - Headmaster Achievement Guide 

It's finally done, over 100 hours of editing, discovering strategies and incorporating new tricks. I did LASO 3 times to try make the best video possible. I hope everyone enjoys. Edit - If you have your own strategies leave a comment to share with others 🙂

"You need full shields for a checkpoint" I realized this right at the end of my LASO run with the scorpion gun. The pain and suffering that came from restarting entire sections could've been avoided

my legendary/laso philosophy is, "If you can find strong weapons (Scarab gun) or if you can utilize anything in the game 9Like glitches) it's fair game

6:10 It is very worth it to kill the ultra elite and take his sword here. The sword works with black eye so you can heal much better. It also trivializes the Tremonius fight.

Finished my LASO run yesterday, I cannot emphasise enough how important it is to FULLY UPGRADE YOUR THRUSTERS! The 4 seconds of invisibility that you can spam indefinitely thanks to Bandanna absolutely trivialises some sections that would otherwise be agonising. You can spam it during the long gondola ride and the sentinels won't even see you. You can use it to close the distance to enemies for a shield recharge melee then move back behind cover before they spot you. You can use it to get behind hunters easily. If the warthog launch doesn't work for you in The Road (it didn't for me) then you can just spam thrust your way to the House Of Reckoning instead, only a few enemies spotted me and all they could do was fire at where I was several thrusts ago, they literally cannot keep up with you if you zig zag a bit. Best of all its great for avoiding the Harbingers instakill orbs, at least it was for me.

Thank you so much! I was eagerly awaiting for your guide. :)

A tip I would add is fully upgrade your thrusters. The last perk gives you 4 seconds of invisibility, and with the Bandana Skull you can spam your thrusters and fly through a mission, staying invisible the entire time. Another one would be to always keep a sword on you and go after grunts and jackals last if possible using the sword when fighting large groups. That way you fully heal up and get your checkpoint. I finished LASO a few days ago and only just learned about the full health checkpoint thing during the Harbinger fight so there were many times I died and went back like 30 minutes or whatever cause I didn't fully heal.

Just spent the day collecting all the skulls on easy. Never done Legendary or LASO before, wish me luck!

Something not mentioned here is that if you max out "invisi-thruster" then infinite equipment means you can just spam and scoot through every room without a locked door, which is most of them, and is much faster than room clearing.

With the Adjutant Resolution (monitor fights), it's actually possible to blast off multiple arms at once using the scorpion gun.

TL;DR: Get an energy sword asap, kill Tremonius Jackal adds by Grappling high and taking them out with Grenades, then take out Tremonius shields and finish him with the Energy Sword (he will not stagger until you drop his shields) grab Scorpion Gun (Optional), go get the Duelist Energy Sword from Okro ‘Vagaduun, slick your way to max Thruster level by hunting down Spartan Cores (3 at Outpost Tremonis and several around FOBs make this extremely quick and easy) then just dash your way through all enemies without problems, clear Excavation Site, kill Thav Sebarim for his Arcane Sentinel Beam if you aren't using the Scorpion Cannon, use the Energy Sword/Scorpion Gun or Arcane Sentinel Beam + Thruster spam to take out any enemies you are forced to deal with, the Gondola with all the sentinels can be skipped by clinging to the wall entirely until you reach the end the sentinels won't spawn, kill Jega 'Rdomnai and take his literally busted Energy Sword over the Duelist one and absolutely blast through the remainder of the game with god tier weapons and beat the last boss easily. I beat LASO in 1 hour and 45 minutes and I know people are clearing faster with those methods. Seriously, no enemy can deal with infinite invisibility, it makes LASO in Infinite easier than Legendary by a mile. Great video showcasing just how silly LASO can be :)

As soon as you get cloaking thrusters, the whole thing gets significantly easier and faster, by just spamming it everywhere past enemies, with the variant duelist sword to refill health. Nice to see you post a tutorial for people that haven't done it yet. I also grapple skipped all the rooms, bridges, elevators, and gondolas, I wasn't forced to activate, by spamming grapple at walls and ceilings.

Having the duellist energy sword in my back pocket for the whole playthrough was a huge lifesaver for me

Thanks for this, just doing LASO myself and there were definitely some tips here that would have made things easier. Love the vehicle skip you do to the house or reckoning.

Awwwwe yeah awesome video! Personally I get the tank cannon, skip the dig with the laser trick and max out the dodge power so you can just invisibility the whole way hehehe

I finished the AA guns but I'll still watch this tip,Laso is very easy but gotta say, you are a legend bro

Haven't even finished the video yet and I'm shocked at how he skipped foundation because I did not know these skips, you're amazing man, atleast you'll help through the 3rd half of the game! Thanks bro

I was waiting for this video thanks Mint👍much love from Seattle!

You're the man, Blitz. Thanks for all your hard work!

Been waiting for this! Great work man, excited to turn on some skulls!!!

Thank you so Mint Blitz! Just completed LASO, your guide made this much easier!

Dude you’re the man - so much I didn’t know and REALLY appreciate.

Thank you! First ever LASO clear done in 6 hours. This helped me a lot!

Thank you very much, I did it with your guide (without the excavation site glitch but with the Scorpion turret) and I must say it was so helpful the LASO was a piece of cake. Thank you kind Sir !

I appreciate the tips and tricks man. This is by far the easiest LASO, was able to do it all in one day just playing a few hours at a time. Thanks for all that you give to the Halo community!

Just started LASO yesterday after beating the campaign on legendary. This was helpful

Honestly I haven’t watched you in a while. But I’ve always been following waiting for the next halo to come out. I’m glad it’s came out because your videos are awesome!

Thank you for the help here. I followed this guide for a week slowly playing through it. I found that maxing out the thruster and using a sword really made things a lot easier. I also picked up jegas blood blade after the boss fight and it made it even easier. Wouldn’t have been able to do it without ya.

Awesome guide, thank you for putting this together. I ended up deciding to do my scorpion gun run yesterday and did finish it. It was not an ideal run at all. Yeeting the brute brother across the map and having to find them. Doing "The sequence" on foot. Trying to get a checkpoint between the blade master and Eschrum was annoying, no idea I could have just quit and restart. and that phase 3 harbinger fight was just insane, nearly two hours on that alone due to the skimmers always having perfect aim with their rockets. I finally got the timing right and was able to grenade spam/shoot the spawn doors as they open leaving only the chieftain to deal with.

This video couldn't have come at a better time. Was just about to start my LASO run!

Remy, you are an absolute legend! Bless you!

TIP: At 21:19 you mentioned it was a slightly difficult part to get past but I found a trick that I used to not fight the sentinels: I upgraded my thrust to max (which gives you invisibility at the end of your thrust for 4 seconds) and I just thrusted into a back corner of the gondola every 4 seconds to stay invisible. Super easy to pass if you've maxed out your thruster.

Thanks a million for all the time and effort you put into this guide!

Bro you just saved me hours with that dynamo grenade tip, I had no idea how op they were

I really love your channel, love bro! 🐐🔥

Thanks for this guide! I am ready to take on LASO

Been waiting for this now it’s time I do laso

I wanted to leave a great big thank you for making this video. You my friend are truly Mythic!! I couldn't have finished my LASO run without it. It even helped me get the Forza Veloce achievement too. It's the one where you have to finish the campaign in less than 8 hours. Have a like on this video and subscription to your channel from me. You've more than earned it.

So when the Covenant or Banished scream "Demon" They arent referring to Chief, theyre referring to Mint Blitz

This video was extremely helpful, thank you.

A legend as per usual 😂

Thanks to your guide (really just giving me the courage to do the task) I somehow beat laso in 4:07:26. I’ve never completed a laso nor have I ever tried speed running but GOT DAMN am I proud of this

Thanks man. This might make the journey easier. Keep it up!

Thank you for the amazing content! Keep up the awesome videos! I want to attempt it now haha

Wow this laso looks so much easier than all the other games. Thanks for the guide

Bro thank you so much for this

A big, big, big thank you for this. Just finished. I was in high school when 3 came out and this is my first LASO. People say this is a good one to start LASO, but man I need a nap after this.

This helped me loads with this achievement, thanks so much!

Thanks for the guide it helped quite a bit !

Glad I listen to this video. I would've skipped the entire game and never gotten the achievement. This video was a tremendous help.

Excellent video!

Awesome guide! Maybe I’ll tackle this one day.

Ahhh my blueprint from the don himself has arrived. Been waiting for this so I can start my LASO infinite journey, appreciate you brotha have a good holiday season ! ❤️

YOOOO This is epic!

Thanks for this!

Great video. Amazing work and I now want to beat LASO

Just completed my run tonight. Even with the Scorpion gun and the temporary invulnerabilty laser drill glitch, far from the cakewalk I imagined. Thank you for the guide, Mint Blitz.

I really wish I had watched this video before I did my LASO run lol, would have saved me a lot of time and torture. I did end up discovering the shield-checkpoint thing on my own, so that’s good. Helped me get consistent checkpoints. I’m on the last level now. Tell you what, I think Boom skull actually makes enemies easier to deal with on LASO than on normal Legendary. Using the secret gun I managed to launch Tovarus immediately into the air during his boss and he died on the way back down. Then I did the same to Hyperius. Splatter damage is OP for bosses. I wasn’t able to splatter Escharum like you showed here, but I killed him pretty easily regardless. I’ve also found that the “melee to get shields back” strat works even better if you have an energy sword/grav hammer secondary since their main attacks count as a melee. So many of the skimmer sections I was able to beat doing that because a) they gave me shields when I did it and b) sword is instant kill for skimmers, even with Mythic. Even Brutes with the rockets are two hit kills (sometimes three) and it stuns them relatively consistently after each hit. A bunch of other stuff I wish I knew though. The grapple fly, the sentinel beam strat for the Nexus (holy shit the section with the nostalgia berries and the shock sentinels actually gave me anxiety), the fusion coil cheese for Bassus and Jega (I got one hit killed in Escharum’s fight and it made me repeat Jega’s boss again. Thankfully I managed to get a melee in with my sword before killing him again and it gave me a checkpoint immediately after killing Jega). One odd quirk with the Blind skull I’ve noticed is with the shield recharge sound. Normally there’s no sound for it at all with Blind. It doesn’t beep if it’s down and it doesn’t make the recharge sound. HOWEVER, if you hijack a vehicle it counts as a melee, so it’ll recharge your shields. Not only that, but for some reason, in that specific instance, it’ll make the recharge sound. Not sure if that’s a bug or not, but it seems too weirdly specific to be intentional. Another weird bug I discovered during my run was on the bridge section of the first level. I managed to get through it all and destroy the engines, triggering the escape sequence, only to die to a box being flung at me, forcing me to redo the bridge section from the beginning. However, for some reason, this doesn’t disable the “escape state” for the ship, so the alarms will continue to blare and the skybox for outside the ship will be briefly glitched into a white texture. The texture part seems to fix itself after a second, but the alarms keep going off. Not game breaking, just thought it was funny.

this guide is going to be so helpful, gotten through the tower now, gonna go do invulnerability and then go around destroying everything to get max valor and all the spartan cores to make the rest of the run less painful

Beautiful

Thanks, papa Mint! This helped me grind it out before season 2 took away the tank gun

I thought this was friggin impossible until I remembered the Bandana skull.

Thanks for the guide. Can’t wait to start my legendary run

Thanks for this guide! I beat LASO (also my first) in 4 hours and 13 minutes of in game time.

Great video, I found that tank cannon and energy sword was most efficient, took me around 4 hrs. Was great fun to have a super lethal mode instead of having to cheese everything like previous games

Thanks for the guide...incredibly helpful...especially that skip for The Road...even with a tank gun, doing LASO normally through that mission would've been awful.

Thank you bro, you’re a legend. Got it done in 10 hours with your guide. I usually don’t attempt LASO mode, but this one was fun and approachable. You’re basically OP with tank gun, sniper rifle and full shields.

A tip for the gondola with sentinels. There are two walkways with a wall on the outside of a 90 degree curve. Stand with your back against it and place a drop wall in front of you. Easy sniping from there on out. In the room following there is a bridge with many sentinels. You can spider man below the bridge to get to the end without fighting annoying sentinels

In the second boss fight, i found that if you jump up on the two tiny ledges next to the trapped spartan, he can't hit you with the sword and he'll stand next to you confused until he switches to his plasma gun. That's when it gets tricky but I had to hop off, and shoot back while switching sides using the spartan as cover the entire time. It tricks the a.i. a little bit when you jump on the sides. Gotta use that scanner each time you switch sides so you know where he is at all times. Such an amazing game. Just about to beat it on legendary myself.

just completed my halo laso run 5 hrs bc of ur video 👍

Thanks so much for this, it helped a lot with my run, prior to this, I was not able to clear Warship Gbrakken

Just beat LASO for the first time since halo 2 (legitimately) This video gave me life thaaaaaaaank you!!

I was having an awful day until I remembered your videos make me happy but I didn’t remember your name so I searched warthog launched and found you! So I better subscribe so I’m always happy

thanks i need this so badly

For Excavation Site, this mission can absolutely be done a lot faster and easier. When I did it, I destroyed the shade turrets beforehand then immediately beelined for the control room after triggering the laser. For each side of the laser, enemies won't spawn until you raise the fuel cells. And if you're using the scorpion gun, it only takes one shot to destroy both. Relative to the laser, the one on the left can be done very quickly and you can get back to the grav lift before most enemies spawn. The other side, I like to go up the ramp to the cliff and take everything out from up there. When you do that, you'll just have a few sniper jackals to deal with and some shield jackals in a cave and not much else. You can melee one to get your health back before the boss fight if you take any damage at all

Having the thrusters maxed out and zooming around with an energy sword was the funnest time I had playing laso.

My trick with the skimmers is actually used to gravity hammer If you get up close to them they don't shoot they're rocket launchers, you can clear whole crowds with the gravity hammer I really used a gravity hammer for most of the my run, Dynamo grenades into gravity hammer, my secondary weapon switched from rocket launcher to needler to Sentinel beams

Just completed it. Thanks :)

If it wasn’t for this video I never would have completed it. Thank you.

Great video

Been waiting for this. Thanks for the great content!

Did my LASO run on my own a few years back, WITHOUT the tank gun, and it took me around 20 hours. I used the special energy sword and the special rocket launcher basically the entire run. Shock grenades are pog, and the unlimited grapples saved my life multiple times.

I find it amazing people find these short cuts/glitches. I hope most play it without at least once or its like sitting down for a good meal and then scoffing it as quickly as possible. Kinda defeats the point of it. Good vid. Very interesting overall.

I found a great strategy for the brothers on pelican down, all you need is the BR and take out Tovarus first. there is a spot all the east near of where he stands, thats where the BR is. All you have to do is just go far enough out of his range and just mow him down with the BR, takes a while but he won't be firing back, he'll just take laps but as long as you have threat sensor you can see him, he ends up going back to right below the platform and just stands there. Next, for Hyperius, he'll be off his chopper by now, use thruster to go across the map to the west side and there is a rock formation by the metal pillars that lets you do the same thing, except I used the rocket launcher and sent him flying off the map into the ring and boom 1 shot kill xD

I did it man! Used the scorpion gun. Only thing I maxed out was thrusters, which came in handy. Should have done shields too but oh well. Thanks for the guide!

Thank you so much

That infinite Invisible thrusters is really helpful in the final section and the last boss fight.

Excellent

The first two missions were so hard, but now I'm cruisin'. Its actually really fun to play LASO in this one. I hope it stays this way lol.

This vid is mint

I'm finishing this this evening, started my run yesterday and on mission 9. The shock grenades are a life saver 😎

1:59 that’s what’s screwing me over! Was wondering if it was because I had the scorpion gun. Good to know

Infinite LASO is almost like a mix of halo and spiderman😂

I was getting the absolute worst checkpoints on the house of reckoning. This video definitely helped. I was raging because of Escharum killing me in one shot

For Chak like, you can throw the threat senor on the central pillar and look up. Their is a tall cavern that you can grapple up. I cheesed the fight in about 5 minutes by constantly grappling back the cavern and tossing shock grenades down. Chak Lok will stand under you the entire time.

This video needs a million views.

Pro tip: Keep a sword on hand and with the infinite grapple you can fly around like your multiplayer's worst nightmare and deal some serious damage. Especially useful in the room with all of the skimmers where Despondent Pyre dies. Its near the end of the Conservatory mission 6

This is definitely by far one of the easiest ones and I also finished In about 6 hours without the cannon 😄 congrats dude

For anyone struggling with the Brute Chieftain in the Auditorium, he's actually super easy. Get him coming at you around the dome the Harbinger is in and just walk backwards around the dome. Whenever he starts to attack (90% it's just a swing attack), thrust straight backwards. Use your gun of choice (no-scoping him in the head with a sniper was my go to, it drops him really fast). Rinse and repeat. Coincidentally this was the same strategy I used for the Harbinger. No-scope her with a sniper and just thrust whenever she teleports out of your line of sight to dodge her melee attack.

I’ve been dreading starting my first LASO campaign, and still am. On this Friday, I am going to start the Halo Infinite LASO and use as many exploits, glitches, and anything else as much as possible to insure it’s completion
