Nukliex

Nukliex is a single-player action game.

The player controls a small spaceship that can move in all directions, but can only fire forwards. The player must travel through 4 stages of rapidly moving enemy asteroids and alien vessels, where the enemies rapidly replenish as they're destroyed. After enough are destroyed, the player warps to a new area. They then encounter the outside of the alien ship, where they must destroy enemy defenses and gun turrets. Finally, they enter into the alien vessel, where they must destroy the heart of the spaceship. There are a total of 10 levels of difficulty, and the player starts with 5 ships, but can earn more as they gather points.
