Space Strike: Galaxy Shooter

An Ultimate button charged and ready to fire changes how you play every wave in Space Strike: Galaxy Shooter. You're the pilot standing between a planet and whatever the aliens throw at it next, and that one saved-up shot for the toughest moment is what keeps runs interesting.

The controls are simple enough to pick up in seconds: arrows to move, gas to push forward, Alt to shoot, Shift when you need the big one. That simplicity is exactly why it's so easy to tell yourself one more battle before you close the tab.

It's a free browser game with no registration and no download, running right in landscape mode on desktop or Android. If you're the type who's happiest lining up a shot under pressure, it sits well alongside Hazmob FPS: Online Shooter and Zombie Survival Shooter for more of that same trigger-finger tension.

Play solo, protect what's left of the galaxy, and see how many waves you can clear before the aliens finally get through.

Protect the planets from incoming alien threats by staying alive and clearing each wave. On PC, use the Arrow keys to move, Up arrow for gas, Alt to shoot, and Shift for your Ultimate. Press Esc to pause. On mobile, the same actions are mapped to on-screen buttons for move, gas, shot, and ultimate.

Save your Ultimate for the moments when enemy ships crowd the screen rather than firing it the second it's charged - timing it right is what separates a clean wave from a lost ship.
