Scenes from Flesh Snatcher
Flesh Snatcher is a bloody jME2 fps with fast movement and dodge-bullets gameplay that is low poly and low-tech enough to run smoothly on a netbook (tested: Asus EeePC 1000H).
Most models were made by the author, Arbaro was used for tree generation, FSRad (shared source, noncommercial) was used for lightmap generation. FOSS-incompatible textures from CGTextures were used.
The code license is not all that clear, I seem only to be able to find the jME license in the archive.
