Croteam created their own engine for use in both The First Encounter and The Second Encounter. Named the "Serious Engine", it is designed to cope with extremely large view distances and massive numbers of models, unlike most FPS engines which are developed for a limited draw distance and only a few animating models (i.e. enemies) on screen at a time: it is very efficient, capable of maintaining dozens of moving enemies (often stampedes) even on a modest system challenging the well known id Tech, Unreal or Source engines. The "Serious Engine" can render through both Direct3D or OpenGL and, while it does not support pixel or vertex shaders, it is optimised for Direct3D 7's hardware transformation, clipping and lighting. The "Serious Engine" is available for licensing from Croteam.
