Real Chaingun 1.1 by D. Trabant
--------------------------------------------------------
Installation:
Simply unzip into your Doom3/base directory.
--------------------------------------------------------
A simple yet significant mod, which makes the chaingun feel
more "as a chaingun would": extra recoil, faster rate, better
sound, larger clip, more damage.
This makes the game's chaingun one of the most powerful
weapons in the game, as it should be :)

Enjoy!
