Alien Complex unblocked is a fast-paced survival shooter where you're trapped inside an alien-infested space station and every corridor could be your last. You navigate tight hallways, blast hostile creatures with your plasma rifle, and scavenge ammo and health packs while the facility crumbles around you. The aliens come in waves—some rush you head-on, others lurk in vents and strike from above. Use WASD or Arrow Keys to move, Mouse to aim and shoot, and R to reload when you hear that empty click. The tension builds as you push deeper into the complex, unlocking sealed doors and finding better weapons, but the deeper you go, the nastier the enemies get. Can you survive long enough to reach the escape pod?
How to Play & Controls
- WASD / Arrow Keys: Move through the station and strafe around enemies
- Mouse: Aim your weapon at incoming threats
- Left Mouse Button: Fire your plasma rifle and take down aliens
- R: Reload your weapon before you run dry
- Spacebar: Interact with doors, terminals, and supply crates
Tips & Tricks
- Backpedal while shooting to keep distance from melee rushers—standing still is a death sentence.
- Listen for the skittering sound before aliens drop from vents so you can aim up and blast them mid-air.
- Don't waste ammo on weak enemies when you can dodge past them—save your shots for the armored ones.
- Check every side room for medkits and ammo caches before pushing forward into the next section.
