Futuremark Game Studios have rolled out the latest patch for the zero-gravity shooter Shattered Horizon. This isn't the promised free DLC - you'll have to wait a bit longer for that one - but a collection of additions and changes that altogether make for a better in-game experience.
Amongst the changes and bug fixes, Futuremark have also granted all current and future owners of the game three guest passes to send to any of their Steam friends. These guest passes allow the receiver to download and play the full game for a limited time, after which they will have to buy the game to continue.
The entire changelog for the patch is below.
