At last, we can do tunnel maps that don't suck. lol Of the three game types this one comes in, I'd have to say that DM and TKOTH will probably be the best. I can only see TDM playing well in a full server. The tunnels are pretty big, although having said that you're not required to play underground as I've made it possible to fight above just a easily. Have Fun. Updated to add more cover for the TDM version.
