Insane Spaceships is like a Shoot'em Up, but instead of play like 1 vs 100, this is only a fight between two spaceships. (Player vs AI or Player vs Player).
You can choose your ship, but players have the same weapons (classic machine-gun, and missile launcher). During the game, box may fall from the top of the screen, like Health Pack, or Ammo Pack... and so the Random Pack ! This one can destroy your enemy instantly... but be careful with it ! It may destroy you !
There are no true objectives, just enjoy yourself, and just to keep the greatest possible advance.
