Steve's Favourite Quake Add-ons
The Reaper Bot - This is a very cool add-on. You can play fake deathmatches with fake people. The bad thing is they all have the same color uniform.
Cujo The Attack Dog - This is also very cool. A cute dog that follows you around and attacks bad guys.
TeamFortress - This multiplayer addon has got to be the best addon ever made. You can pick up to nine different classes such as Scout, Soldier, and Demolitions Man.
NOTE : These add-ons require the full registered version of quake.
NOTE : You must have pkunzip to extract these files.
