Developer Unknown Worlds Entertainment has been pretty generous with pre-release support for their upcoming first person shooter Natural Selection 2. Folks who pre-ordered the game have already gotten access to the title's level editor. Now the developer has released an engine test build of the game for all pre-order customers.

The engine test is just that; a way for the development team to see if their in-house game engine will run on a variety of computers. It consists of a couple of levels where your player character can run around in and shoot at animated dummy targets. It does not have the actual Natural Selection 2 gameplay implemented.
