X2: The Threat	Source: Egosoft

A completely rewritten 3D engine based on DirectX8 encompasses many visual effects such as volumetric Nebulae (gas clouds) that have a real impact in the game (you can hide in them), many new engine, shield, weapon and explosion effects. Objects cast real dynamic 3D shadows! Dynamic DP3 bump mapping allows a previously unseen level of detail.
