AfterWorld has released their Survival Tech-Demo for download.
This test-project is technical test of new server architecture and updated engine with enhanced graphics. While in Survival Tech-Demo (STD) we have used terrain from the AfterWorld: Survival project, it is completely separate game with its own logic and rules. Keep in mind that in order to play in STD you need to have a valid account in AfterWorld: Alpha World and your avatar should have citizenship.
