Accompanied by your co-pilot Annie, you must navigate through a barrage of alien bad guys who are determined to end your mission.
This title leans heavily into its retro roots, offering a straightforward combat loop that prioritizes precision and positioning. The screen often fills with multiple threats, forcing you to make split-second decisions about where to move and which targets to prioritize.

How to Play
To start your mission, use the WASD or Arrow keys to navigate your starship across the screen. Your primary goal is to destroy the alien bad guys before they can overwhelm your vessel. Use your mouse to aim your weapons at the incoming threats. You can fire manually by holding down the left mouse button, or you can press 'P' to toggle the autofire option for a more streamlined experience.
As the rounds progress, the number of enemies will increase, requiring you to stay mobile and avoid colliding with alien ships or their projectiles. Your co-pilot Annie is there to assist, but the survival of the ship depends on your reflexes. Watch for patterns in enemy movement and try to clear out groups before they can surround you.
There are no saves or persistent upgrades, so each run is a test of your immediate skill. The game continues through endless rounds, challenging you to see how many alien waves you can defeat before your ship is destroyed. Focus on balancing your offensive fire with defensive maneuvering to achieve the longest survival time possible.
