You are Max, on a mission to find your missing brother. Your only lead takes you to an old Soviet R&D Institute, now taken over by mercenaries and creepy results of human experiments.

Fight your way through enemies, complete quests, and go deeper underground with each level. The more you explore, the more secrets you uncover about what really happened here.

Gear up, stay sharp, and get ready for a dangerous journey into the unknown.

Fight against monsters, mercenaries and bosses as you head into an abandoned mega structure.

Search every corner for useful gear, supplies, and valuables. Everything you find can help you survive — or be sold later for profit.

Stock up on food, water, ammo, and meds. Once you are inside, you are on your own until exits open. Complete tasks, find better gear and upgrade your stats to improve your chances for the next raid.

Make it to the exfil point to keep your loot — or die and lose everything you found and brought with you.
