Debris

Debris is an Asteroids clone for Windows. Players control a ship that can be moved around freely in a single-screen 2D environment, shooting asteroids into tinier pieces until they are completely destroyed. It features a two-player player mode (both cooperative and competitive) and a level editor, here called a Wave Editor. For retro gamers who want to remember the look and feel of the original version, the game also features a Retro Preferences section where you can disable the improvements such as the end level boss ships (and not the simple flying saucers) or disable the Rapid Fire bonus.
