Armored Core 6 - Speed Farming Wall Climber Mission l Speed Farm Guide 

But you have to take into account all the time wasted ending and starting a new mission + load time + the speech at the end // and the fact you don't get 90k out of the mission but actually more around 75k

I properly tested multiple Missions with always the same Setup to get compareable Results. Destroy the AC gives you about 85~90k / takes 70 Secs, Destroy the Helicopters gives you about 95~100k / takes 70 Secs (Note: 95~100k only if you also kill the 4-Leg at the End). Which makes Destroy the Chopper the better one of these two. Now this Video here shows that you can get 360k in about 243 secs. To get 360k in Destroy the AC for example you will need 4 perfect Runs, which would take approx. 280 Secs combined (which is already 40 Secs slower than one run in Wall Climber)... but doing the four Missions also means 4x the Loading-Screens which addititonally slows the COAM/h down. PS: Another great Mission to farm COAM is Attack the Dam Complex. Which can be completed in about 140+ Secs, and grants about as much as twoi Destory the AC and Destroy the Helicopters Runs. But if you got the right Gear, then Mission Wall Climber can be as easy as the other mentioned Missions, but its King in terms of COAM/h.

@@narodekk ooops, didnt see your comment in time. Drifed away, could have saved my time. Absolutely correct, but you can get up to 85~90k if you have the Upgrades/Gear to nuke him quicker. But it still means at least 4x more Loading-Screens (depeding on how the battle goes even 5x more), to get the same amount of COAM, plus the spent time in the 4 Mission already exceeds the time it takes to clear Wall Climber once. But depending on how early people start to farm COAM, Destroy the Helicopters clearly is the better option over Destroy the AC. But only if you also kill the 4-Leg at the End of Destroy the Helicopters. Because that way you get around 95~100k, noticable more COAM but the Mission is exactly as short as the Mission Destroy the AC.

@@Nebujin383 Yup I did it early game (like with gear from chapter 1) - For me full loop was taking an average of 1m30 // with an average reward of 75k. For sure it may become a bit better after that but then you can totally crush the "Operation Wallclimber" very fast (I have no exact data on this one)

Phrasing!

If we count the loading time as well I think Attack the Dam complex is better. Less than 2 minutes for ~180k

Personally I find the wall to be a much more fun & engaging level, which is a good trait for a grind

It's also a great mission for testing out builds early on

I also prefer that one just due to its ease - not quite as fast as Tester AC but faster than Wallclimber and not build dependent, so I'm able to bounce around with a bunch of non-meta stuff and still get around 170k; my best has been 185k and my worst I think was 163k Also, even though I can do Wallclimber quickly I like killing all the stuff on missions that give bonus pay, even going out of my way to melee as much as possible to save on ammo costs but that's less time efficient.

Yea well, shouldnt try to farm this Mission too early for COAM, come back after first Playthrough xD
