You wake up on the Biologic Space Laboratories station with your Power Suit half-eaten by an X parasite, and you've got to claw your way back to full strength one upgrade at a time. You run, jump, and morph into a ball to slip through tight ducts while blasting X organisms and hunting down the SA-X, a deadly copy of yourself that stalks the station. Every locked door, missile pickup, and boss fight pushes you deper into a sprawling map you'll want to explore inch by inch. Beam upgrades let you melt through obstacles that stopped you cold an hour ago, so backtracking actually pays off. Can you survive the station and take down your own shadow?
How to Play & Controls
- Arrow Keys / WASD to move, crouch, and aim
- Z / Space to jump, X to fire your beam
- Down twice or a dedicated key to roll into Morph Ball mode
- Shift or A to fire missiles once you unlock them
Tips & Tricks
- Shoot every wall and flor block, since hidden missile and energy tanks are tucked behind fake surfaces.
- Save often at the navigation rooms because the SA-X hits brutally hard and won't wait for you.
- Use Morph Ball bombs to reveal cracked floors and reach areas your jump can't touch.
