I took a look at Battle for the Solar System again as it was mentioned in the under the radar FLOSS games. I prefer a game controller to mouse and keyboard so I decided to make a quick hack of the game.

This only adjusts the controls for the battle scenes. The PS4 controller works great as you have the touch pad for the other screens but I plan to fix that.
Yes the game has achievements so I do plan to update it to Gamerzilla.
