SpaceInvasion 2
SpaceInvasion 2 is the newer version of the game with modern graphics. Our community loves the classic retro style, so we mainly focus on SpaceInvasion (Classic). If you prefer the more modern look, you can start SI2 right here.
SpaceInvasion Classic and SpaceInvasion 2 are two separate games, each with its own wiki. Many things work differently in SI 2, and some exist in only one of the two games.
