Forgot to say, we use OldSkool for graphics - want to see your own creations in ForeVox? Create an awesome baddy using OldSkool Designer (http://www.kongregate.com/games/pintsized/oldskool-designer) and we may feature it in the game!
Developers: Source code for rendering OldSkool voxel models in Unity3D has been added to the Apache 2.0 licensed oldskool project on Google Code: http://code.google.com/p/oldskool-voxel/
