Gratuitous Space Battles aims to bring the over-the-top explodiness back into space games. The game is for everyone who has watched big space armadas battle it out on TV and thought to themselves 'I could have done a much better job as admiral'. This is not a game of real-time arcade twitch reflexes. GSB is about what ships you design, and what you tell them to do. Your individual ship commanders have total autonomy during the chaotic battle that unfolds. This is not a tactical game, it is a strategic one. These gratuitous space battles are not won by plucky heroes with perfect teeth, but by the geeky starship builders who know exactly what ratio of plasma-cannons to engines each ship in the fleet will need.
GSB has both a singleplayer mode, and a cunning 'asynchronous' multiplayer mode, where you upload a 'challenge' containing your fleet (complete with your custom ship designs and each ships orders of engagement) either to openly challenge all other GSB players, or aimed at a specific player you know. The game has a challenge browser (see screenshot below) and history which shows you who accepted your challenge, and whether they won or lost, and players can rank each others fleets for both fun and difficulty.
If fighting against a fixed fleet of enemy ships (either the default game missions in three difficulties, or player-made challenges) isn't your thing, then GSB also has two 'survival mode' maps. In these battles, your fleet is helplessly outnumbered by wave after wave of enemies that warp in and attack you. Your fleets final defeat is certain, but how many enemy ships will you blast to atoms before you go down with your ship? Check out the scores to see how other players have fared.
