We are maybe late with publishing of this news, but it’s important that news is published and that you can look at this game.
Gratuitous Space Battles 2 is the sequel to GSB 1, developed by Positech games. it is currently in development and targeted for an initial release in late 2014 on the PC/OSX/Linux platforms. The sequel will hold true to the basic theme of the original game, but will have a complete engine re-write, and a vast range of cool new features yet to be announced. We can definitely confirm that the new game will have achievements, multiple-monitor support, and mod support.
Release date of the game is more likely to be in 2015, but who knows.
