Xolstar 3 is a side scrolling shooter. The background moves horizontally left, even when the player is moving or reversing direction. The Xolstar, the character of Xolstar 3, can only endure 3 hits before dying. The player can move horizontally and vertically, but slowly.
The Xolstar fires lasers capable of destroying enemies and objects that get in its way. Objects made of blocks can be hid behind to avoid fire from enemies, most of whom fire is straight directions (horizontally, diagonally).
Xolstar 3 is set in outer space. The background constantly loops. In the background, Xolstar passes several planets, red planets, and green planets. There are also asteroids in space, which can be destroyed by Xolstar's lasers.
