This weekend, Futuremark's space shooter Shattered Horizon will be free to play. Not only that, you can get it for half off this weekend, then it will be free to play forever! The game's normally $20, so it's not a bad deal. Just make sure you've got Windows Vista or Windows 7 because the game requires DirectX 10. There's no XP/DX9 support whatsoever.
If you're wondering how the game is, check out our review.
