Hammer of Thyrion Features:
1. Support for Hexen II, Hexen II demo, Portal of Praevus mission pack and HexenWorld.
2. Cross-platform code: Tested on Linux, FreeBSD, OpenBSD, Mac OS X and Windows. Also reported to build and run fine on QNX and Nokia N770, N800 and N810. Other unices should also work. Even DOS is supported for nostalgic purposes. There are seperate ports to MorphOS, PalmOS and GP2X.
3. Tested on 32 bit and 64 bit platforms.
4. In-game resolution changing for both opengl and software renderers. Instant fullscreen/windowed toggling on X11 (unix).
5. OpenGL enhancements including multitexturing, glow effects, working brightness control, text and hud size changing on the fly, translucent console background, console background stretching, colored lights and support for external lit files, fixes for texture cache and model mesh cache mismatches.
6. Fully network-compatible with Raven's 1.11 windows version as well as with other Hexen II ports. Can load and play games saved with Raven's 1.11 windows version.
7. The same binary handles both original hexen2 and the mission pack.
