Great video! I've dug through the source code you linked, and I think I can give a brief rundown of how the QED random distribution works. First, every effect has a unique, predefined "percent chance" (not actually but I'll talk about that later) between 1 and 100 tied to it. For BO1, these are: Weapon starburst - 75 Disable excavator - 75 Add zombies to total - 70 Revive - 60 Random weapon powerup - 60 Random grenade - 50 Open nearest door - 35 (you showed the wrong code snippet here) Random bonus or lose points powerup - 25 Teleport - 20 Pack/unpack weapon - 10 Give perk - 10 Random "zombie grabbable" powerup - 5 Random powerup - 5 Speed buff - 2 When the QED explodes, the game rolls a random number in the range 0 (inclusive) to 100 (exclusive). Then, it checks all of the effects against that same number. All effects with a chance value greater than the rolled number (you can just think of this as the chance number being a percent chance for this) AND a valid player state (i.e. a player needs to be down for the revive) are eligible. Then, the game randomly selects one of the eligible effects with equal distribution. For example, if the game rolled a 64, then only the "weapon starburst," "add zombies," and "disable excavator" would be eligible, and the game would choose one of those three with equal probability. If the game rolls a 75 or higher, then you get no effect. Although, this is not the only way to get this effect from a QED. Because the game has two different sources of randomness (once in choosing eligibility and once again in selecting the effect), the numbers above aren't a realistic percentage. The way BO1 calculates this, all effects with a chance value higher than the rolled value will be eligible (given valid player state), and then selected randomly. This has the effect of making rare effects even rarer, because those effects need to compete against every effect more likely than itself. After some calculations, I estimated an approximate probability for each of the effects here. It's worth noting that this is just an approximation, as the probability of an effect can change given the state of the game. I have included ranges for effects to accommodate for this. The more conditions are met, the lower the probability of any individual effect. Do nothing†: 25% Weapon Starburst: 14.33% - 46.5% Disable excavator*: 14.33% - 27.4% Add zombies to total*: 11.83% - 24.90% Revive*: 8.49% - 19.90% Random weapon powerup*: 8.49% - 14.26% Grenade: 6.49% - 21.50% Open a door*: 3.99% - 8.65% Random bonus or lose points powerup*: 2.56% - 4.68% Teleport: 1.94% - 4.90% Pack/unpack*⸸: 0.83% - 2.40% Free perk*: 0.83% - 2.40% Random "zombie grabbable" powerup*: 0.37% - 0.68% Random powerup*: 0.37% - 0.68% Speed buff: 0.14% - 0.5% * Assuming the game state is met, i.e. a player being down for the revive or an excavator being active to be disabled. For the powerup drops, the QED has to be within the playable area. ** The free perk has a 20% chance of being invalid, just for funsies. † This is not the only way a QED can do nothing, but it is a major factor. ⸸ Pack/Unpack is always valid when the QED is thrown near Pack-a-Punch, but has a 20% chance to be valid without it. I didn't factor this into the calculations because I am lazy. For BO3, the logic for selecting the effect is the same, although as you mentioned there are fewer effects. Diving into this was interesting, thanks for the opportunity
Thank you for diving into this! This is actually super interesting how the game chooses which effects are to be selected from then selects randomly. I'm very glad we're coming together as a community to actually break down and learn more about the game, even all these years later!
Thanks for looking into this mate :) Took me a while to realise "Speed Buff" was referring to the Zombie's sprint state XD. Btw, is that effect permanent?
@@frex102I figured as such. When I tried it on bo1 I got it on my second try but I spent a good 15 minutes (at timescale 2, so really 30 minutes) just spamming it in game and didn’t get it to work. Just goes to show how random the QED can be!
@@MrJzMI would have thought that you have to throw it at the console you hack to disable them in the spawn room but I don’t play enough Moon to know that for certain
@@acupncture833 on bo1 you throw it at the digger itself; I didn’t show the footage in this cut down video but it’s somewhere in the full footage. I assumed the same would be true for bo3
@MrJzM with all do respect I think stuff was removed in the bo3 moon or rarer than happening in bo1 moon I have gotten the gersh devices from qeds and the zap guns but I've never seen footage of that happening on bo3 moon
I’ve always wondered about the QED downing players, this explanation makes a lot of sense! Only critique I would have for the video would be to show each effect as you describe it, it’d be cool to see them go off live
@@Wunderfulx honestly I tried to do that but certain effects are actually insanely rare (free perk bottles on bo1, or for whatever reason disabling excavator on bo3[?!]) and I didn’t want to show only some of the effects and not all of them
As someone who did the rainbow perk challenge on BO3 moon using QEDs one massive thing that people don't realize is that by spamming the QEDs you actually severely reduce your chances of getting something like a free perk by spamming all 3. For example you won't get a free perk if another QED is active with a spinning weapon. I believe this also affects other players also throwing QEDs so when we were doing the challenge we had to take turns and wait for the blast or spinning weapon to finish before throwing another. & also at least in BO3 the free perk is completely random in regards to the number of players in the game who receive it.
Dude what are you talking about, it was on bo1 that it could give you a free perk, on bo3 the chances are so low its about 1 in 1000 chance, the moon map i play the most on no1 and bo3 and let me tell you that barely any of you guys play this map like barely anyone, they are to busy playing easier maps
@@cantthinkofnameyeah7249 its rare man very rare. Its even lower odds on bo3, heck qeds are able to relocate doors but oj bo3 they lowered the chances on all the good stuff by miles. Its the map I play the most
@@z304legend yes it's rare but the "1 in 1000" claim may just be from someone testing by spamming. Unless of course you'd happen to have specific proof the code says so but the point I'm trying to make is that players spamming all 3 QEDs at a perk machine at once is really what decreases the odds of it happening. Acts as if certain effects are not possible to trigger while another QED is still active with something like a spinning weapon. I've literally done testing of this with multiple players all spamming QEDs vs players using one QED at a time. The fact that 2 of us were able to complete the rainbow perk challenge that game should be extremely telling of my point. I'm not out here making baseless claims with this nonsense. I'm speaking from true unmodded gameplay experience
These amounts of misinformation is why every game should have an official wiki and not a fandom one, not only would it have a better ui (not hot garbage full of ads and ai generated q&as) it can also be locked down and be edited by people who ACTUALLY KNOW WHAT THEY ARE TALKING ABOUT.
The downing of players can also happen from the spawned weapons. Just a few days ago had it spawn an explosive weapon that shot in a circle and downed 3 out of 4 of us lol
I'm not certain but you may have to throw the QED at the actual machine you hack to stop the excavating. Moon is such a cool map with sooo many hidden secrets. Few of my homies actually completed the EE on round 1 recently. Wouldn't have been possible without the QED's. W vid btw 💚
I have seen the gersh qed effect before in my game. I went to revive someone and said screw it ill try this. Threw the qed at my buddy, it made a black hole i ran into by accident and was taken so far away i couldnt get him. (B03) he died that day.
@@MrJzM it was different from the gersh device. Just a single black hole spawned. Iirc, it was round 24 or higher and we both thought it was weird that we didn’t get any gersh devices that whole game
Been playing since WAW, and haven’t encountered all of these effects yet, most recent was throwing one at pack a punch area and getting dragged back behind the horde I was running from, what are the odds?…
I know some code, but this is too complex for me and I lack some context, either way it seems that the probabilities are defined in the init() function, around the lines 60-80 (in BO3, haven't checked BO1)
What is the chance to get a free perk when throwing it at a perk machine? Is there an estimate you can give. Ive thrown about 180 qeds at perk machines and got the free perk 3x.
Going into the code isnt always going to confirm everything. Were still finding hiden code in zombies 20 years later that only shows when specific things are met
@@NeCoruption well, no. These are the decompiled scripts which show all of the possible interactions the QEDs have. There is no hidden code that wouldn’t be in the scripts, and the only hidden things that are being newly discovered are from scripts that have been in the game that are being decompiled for the first time, of which none are left on Black ops 1 (and 2 and 3 and 4 and cold war)
@@NeCoruption the impossible easter egg isn’t a quest that can be triggered in game; otherwise we would have discovered it. It’s physically impossible to hide an in game trigger in the code. The QED cannot have more effects than what is written in the code
@@MrJzM Claiming there isn't any footage of it without searching is just lazy. However, it doesn't mean there isn't lost footage. For all we know , it could have been an unintentional glitch, but it most definitely happened.
@@MrJzM unfortunately not, but i could probably go back into the game and do it. Though my game was modded using AAE so potentially that could of caused it
I just looked on the AAE mod page and one of the changes listed is "Fixed an issue where a Quantum Entanglement Device was missing some effects," so yes the mod is most likely why. Source: steamcommunity.com/sharedfiles/filedetails/?id=3017924565
Who the fuck was believing Anti Fire sale 💀💀 Funnily though, I have never actually seen any effect from the QED's. Admittidly i don't use them often, and only used them for the EE and to try and get some perks, but yeah it never gave me the perk cos i was unlucky and i didn't get to see any other fancy effect :(
I can personally deny the myth of the anti fire sale being fake. I usually get that effect when I am using the QED on moon and I hate how much money I have to waste because of the anti fire sale 😢
Yeah ypu want answers by someojr who doesn't obsessed with making videos for money fot doing things plenty of others did then ask me. Qeds were way better on bo1, on bo3 they took away many of the effects, like on bo1 qeds were able to relock doors, give you perks, give you guns take guns away, give you thr wonder weapon, be able to upgrade your guns and even deactivate the big diggers and more but on bo3 they took away A LOT of what the qeds could do making them super lame. On a unrelated note on bo3 you can break the jump pads where you can stay up in the air but in bo1 it will always throw you to the next jump pad. I love the moon map heck the idea of the moon wad actually stolen, the map was supposed to he in Paris till a few months prior a couple of us were talking in game with randoms and then the map changed to the moon, but I still love playing thay map.
As a very casual bo1 player, i believed the qeds did literally nothing for most of my life. I didn't even know their names. In my houshold, they were called "garbage grenades" and completely ignored
My favorite QED effect I personally used was a double revive. In a three player game, I went to revive my buddy, I backed myself into a corner and new I was about to down. I threw a QED praying it would revive him. I then went down and it exploded and revived him and myself. It was so clutch
The fandom wikis have so much misinformation for countless games. I’m always glad to see it cleared up. Btw this video deserves orders of magnitude more views.
Out of curiosity. Because I play alot of game's where I often times rely on the wiki for info, which fan wiki have you noticed that spreads misinformation?
@@PleaseTryAgainLater It might be better now but I believe the Risk of Rain 2 wiki used to have a lot of inaccurate info. Honestly I was kinda just repeating a common sentiment so maybe I’m also spreading misinformation.
Went ahead and updated the wiki since yk, anyone can update it. Thanks for clarifying this info and helping with the whole misinformation problem this community has
The amount of times I tried to create camping spots in BO1 by closing doors with a QED. Pretty sure I saw it on the wiki back in those days too! I swore it must have been fake. Sucks it's not a thing but at least I was right lol.
You are correct in the accidental teleport kills! Sometimes the game doesn’t check where it sends one player before sending another and that leads to two players occupying the same space and one being teleported above the other subsequently resulting in death.
I remember back in the BO1 days my friend told me it could spawn the thundergun. I don't know how many hours I spent playing moon just trying to get the dang thing to spawn one only to find out it wasn't possible.
“Maybe it was because of gobble gums and they thought it was redundant” My friend, having to spend money to use a now defunct otherwise feature is not redundancy.
QEDs can absolutely cause a gersh black hole effect, happened to me and my cousin while running the moon easter egg, its possible to effect is limited to that map though, and possibly the same idea with some of the weird neiche affects that where listed could very well just be map specific. But ya, ive definetly seen it spawn a gersh hole 🤷
Just a heads up for anyone. This exact wiki page is un moderated and practically most of the information on it is false or mislead information. There are a ton of videos about why and how! Educate yourselves! It's very interesting.
Also for the negative power up drops aka the red ones They can also be grabbed by zombies to affect you so if you think you're safe not grabbing that red perk bottle make sure there's no zombies
The BO3 chances are as follows, according to the code: "random_lethal_grenade" - 50% "random_weapon_starburst" - 75% "pack_or_unpack_current_weapon" - 10% "auto_revive" - 60% "player_teleport" - 20% "zombie_speed_buff" - 2% "zombie_add_to_total" - 70% "zombie_fling" - 100% The game generates a random number between 1 - 100 and discards every effect with a chance less than that number. Then one of the remaining effects is chosen randomly with equal probability.
Thank you for doing the work to get accurate information. It seems like most, if not all, "informative" Zombies RU-vidrs are regurgitating entries from the extremely sketchy wiki. Doing research and citing sources are beyond this community.
Dude you can get the pistol back in bo2 as long as one other person still has the pistol. , also funny how you're going for high rounds on moon on bo3 seeing how bo3 is SUPER EASYZ even without gums
Sadly almost no one plays yhe map anymore and barely anyone plays it on bo1, I bet your butt most people here saying they love the moon map probably never really played it as much or dojt play it now really, remember most folks are fake and want to look cool and good
I'm pretty sure i've seen the vr-11 effect and anti firesale before, why you didn't find it in the code is anybody's guess but maybe it has something to do with you not looking at the official copy of the game but the plutonium version which is a modded client. And the QED nerf is the reason why i always prefer bo1 moon over bo3.
@@blauwbeer556 you have 100% not seen that before. No footage of it exists, and it has never been possible. The scripts I linked were posted by plutonium but they are completely vanilla scripts
@@MrJzM Listen dude, do me a favor and don't act like a dick. If you don't believe me then that's fine, i'd also be suspicious of rando's on the internet but that doesn't mean you can get away with having this attitude. Do this too much and you'll cultivate a toxic viewerbase.
@@blauwbeer556 I’m here to stop the constant misinformation that spreads throughout the community, and you claiming you saw it perpetuates it.

@@MrJzM You missed my point entirely, for the sake of argument let's say you were right and i am a malicious QED rumor spreader, how would my response be wrong? A couple of months down the line with this shit and you won't be able to read the comments at all because they'd be that bad, take a chill pill. It's not that serious, in my original comment i even talked about why i liked bo1 moon over bo3 because i thought this was a semi-casual space where fans of the gamemode can come together discuss their opinions.
@@blauwbeer556he didn’t have a problem with your opinion about liking bo1 better. He had a problem with you saying you’re pretty sure you’ve seen those effects before when nobody has ever shown those effects and he wasn’t even being a dick about it he was just saying you haven’t seen it before cause nobody ever has and if you have give proof that’s literally it
