CustomTF is a Quake mod based on Team Fortress. As in TF, you can choose from 9 stock classes. CustomTF has a tenth class – the custom class. Custom players get a sum of money to buy the loadout of their choice. Weapons, health, armor, speed and extra skills can all be bought for varying amounts of money.
If you want to play, connect to trumad.dyndns.biz in Ezquake, or check out the other servers currently running.
If you don’t have CustomTF, or even Quake, head to the downloads page to find an installer that’ll get you going in no time :)
