Gratuitous Space Battles provides a hands-off take on massive space battles. You customise your entire fleet, right down to the weapons and shields on each ship, and then set them up in formation and set them loose on the enemy. It combines chin-stroking strategic planning with explosive space-blam on a massive scale. The latest expansion adds new graphics, a single player campaign that lets you fight fleets designed by other players, and the ability to capture enemy ships.
Here's a list of the new features added by the latest expansion.
The expansion's available now on Steam and from the Positech Games site. For more on the game, head over to the Gratuitous Space Battles site. If you like the idea of massive space battles without fiddly mid-battle micromanagement you might want to check out the demo .
