2fort4 Is a map that has 2 forts.
This two-team Capture the Flag (CTF) map has a fort or base at each end, with a "moat" between them, and a bridge to cross the moat. There are underwater tunnels leading into each fort, so that you can get in there without being detected by the people outside
The objective of this map series is to grab the enemy flag out of their basement, and return it to the center of the battlement on your fort. Doing so will award everyone on your team 10 frags.
