Marine's Best Friend is a modification of the Doom source.

Features

* Friendly Monster AI
  + Friends attack enemies like players

DISCLAIMERS

MBF is unsupported software. There are no warranties as to its fitness for any
particular purpose. There are also no plans for future updates.

MBF is a single-player game. Multiplayer games may or may not work (some people
say they do work). Support files for multiplayer games (e.g. sersetup.exe) are
not included, but might be available elsewhere.

MBF is based on the Boom v2.02 source, but it is not supported by TeamTNT or
id Software. Don't ask them about MBF.
