The heat_vision_patch.zip file you have requested: Mods / Graphics Enhancements / Heat Vision Patch - 1.12mb is not available. Perhaps try browsing all files for the game Aliens vs. Predator 2 and upload any files you want to share or are missing. This is the only information we could locate:
The humans in Predator heat vision are redone to a yellow, orange and redish tint instead of the default blue and green. This works in both 16 and 32 bit texture depth. Different classes give off more heat then others and all are viewable in heat vision easily (like they can hide anyways).I will do other versions of this soon. But this one is damn fun to use ingame. Only the default characters are changed. Ichiro, Harrison Jones, Johnson, Rykov, Dimitri, Ivan and Dunya. The best thing about this is that you can apply it and join ANY server. Enjoy the new mod.
