This modification is made to alter the graphic output of Crysis Wars (Crytek GmbH) to make it appear hand-drawn. It is possible to play it in the original game maps, it does not require any configuration and it works in DX10 and DX9.
Cell shaded image rendered ingame.
Why is this only for Crysis Wars? Looks cool though. Far Cry did this, always wondered why they didnt include it in Crysis.
