Mercenaries, the hot wind blows... the snow is melting... the air becomes polluted... and we detect the very presence of Gray Mann's Armageddon, but his robots aren't playing around anymore. They've taken on a gruesome approach that only the most talented warriors can handle. How rude of them to disrupt the aftermath of America's Independence Day... only now have they decided to really get serious. Did Gray Mann even plan any of those attacks? Has he been failing miserably until now? No matter the answer, reload your weapons, prepare your explosives, fill up your canteens, and stock up on upgrades because this war is where Gray Mann is the most red-blooded he's ever been, it will be the final war if you don't plan accordingly...
Operation Lithium Lunacy is a brand new Mann vs. Machine charity event brought to you by Abyss MvM featuring 9 intermediate, 9 advanced, 2 nightmare, and 10 bone-breakingly hard expert missions across 28 maps. Complete at least 6 missions to earn in-game medals! Event servers are available worldwide in North America, Europe, Asia, and Australia. Click here to get started!
Is that all of the missions? Have you thought Gray Mann's limit test in the fall of 2023 was too easy and short lived? Think again, because now you can play a total of 3 master difficulty missions. This is crazy, right?! After 3 years, Abyss MvM has secretly worked with Gray Mann to create 3 new super hard missions designed for the fearless, challenge-seeking warriors among you. Alongside them is a returning master mission from the fall of 2023, redesigned to fit what we'll call the "new skill level" of our willing contestants.
