Quake 2 Map Info is a command line utility that parses a Quake 2 map file and reports how many entities and textures are being used. It is useful for spotting extra items to improve gameplay balance and/or reducing extra textures to increase map speed. Most map editors do not provide a detailed breakdown of what is inside a map. It is compatible with any Quake 2 (ID Tech 2) game engine if the map file format has not be altered. If a game has a different map format, you can modify the source code to reflect the new format.
Py-Lepton is a high-performance, pluggable particle engine and API for Python. The engine is designed to be very flexible and does not rely on any other libraries directly. You can use it either with OpenGL (via pyglet or PyOpenGL), or with pygame by selecting the appropriate renderer. Examples are provided using pyglet and pygame. Note that this is in an alpha state, so expect the API to change somewhat in future releases.
Alpha Shooter is a 3D first-person shooter game with a sci-fi setting. It features multi-platform support (Linux, Mac OS X, CygWin, and Windows) and, since version 0.1.0, its own reusable game engine (Neutron). The game and its engine will evolve over time to incorporate simulated physics and AI, networking, audio, scripting, and more.
Warsow is a standalone, eSports-oriented FPS game. It is based on Qfusion, an advanced modification of the Quake 2 engine. It features fast-paced gameplay focused on trix (trick jumps) and art of movement. War§ow features a complete power-up system, including weak and strong fire mode for each weapon in all "normal" gametypes as well as Warshell (battle shield) and Warshock (quad damage) for team-based gametypes. Its cartoonish graphics use cel shading with a style that is similar but not identical to Manga.
