This incarnation of the Lithtech engine is Jupiter Extended (or Jupiter EX for short), which was featured in the highly rated games F.E.A.R. and Condemned: Criminal Origins, both developed by Monolith. Compared to its precursor Jupiter, the Extended version is driven by an all-new DirectX 9 renderer and has seen some other major advancements, including the addition of Havok physics to simulate realistic physics. Along with Havok's character dynamics, Jupiter EX includes also the Havok Vehicle Kit, which adds support for common vehicle behavior.
