My first Quake3 map!
This is version 2 of the clocktwr (not clocktwr2 just a revised edition)
1 ) Extract clocktwr.zip into your Quake3/baseq3/ directory
2 ) Start Quake3
3 ) To The Clock Tower (clocktwr) is built for 3-7 players. There is just about everything in this level except for the railgun and lightning gun. Those two weapons wouldn't be much fun on this map (at least with bots).
