Fight your way down through 50 decks, from the cell block to the drive core, and find out what happened to the crew. WHAT YOU GET • 50 levels in 5 zones: Cell Block, Medical Labs, Crew Quarters, Docking Spine and The Core • Every run is new: procedurally generated decks with loops, side paths, secret vents and keycard doors • 3D mutating monsters: the deeper you go, the less human they are. Shoot off limbs, watch them crawl • A guardian boss at the end of every zone, each with its own attacks • Classic arsenal: fists, pistol, shotgun, rockets, homing launcher and a plasma rifle • Traps that belong on a broken ship: sparking power cables, fire grates, laser gates and security turrets • Elite monsters, specimen tanks that burst open, secret stashes and crew logs to find • Cinematic cutscenes, a full ending and an unlockable Survival Arena around the ship's drive core • Retro pixel look with an optional CRT filter, smooth on older phones • Dynamic soundtrack that kicks in when the fight starts • 13 achievements (Game Center) • Gamepad support, touch controls with a floating stick, haptics • Play offline, any time Fast movement, keycards, sliding doors and secrets around every corner: the shooters you grew up with, rebuilt for your phone.
