Comet Busters! is an arcade game inspired by Asteroids created by Steven E. Hugg for Windows 3.1/95. It was originally released in 1991 as shareware with a registration cost of $9. The latest (and probably last) version is 1.4, which works well in Windows XP, Windows Vista and Windows 7 (although because it is a 16-bit program, it no longer works in the 64-bit versions of Windows) and has also been reported to be playable under Wine. It supports multiplayer with up to 4 players on the same PC or 2 players online, and includes a variety of modes and settings.
