How about for effin TTT maps? I can read the front page of a forum, I'm not THAT dumb.
You requested CS and HL2 in addition to TTT. BKU has weapon spawns for CS maps included with TTT, and most TTT maps that I play on have adequate weapon spawns already placed. If you can't stand the idea of arming TTT maps yourself, there are many maps on garrysmod.org that have been converted to TTT. Regardless, it only takes a few minutes to set the maps up as you will.
