I like the Q3TA CTF. We usually play 4 - 6 people games. usually 5 or 7 players (2-3 human the rest are bots) per team. This makes almost any level hectic! Most of the time, I'm one of the designated flag carriers. This is our team tactic. I can afford to give it away as we don't play on the internet.
5 player:
one Player + lots of mines protect our flag. One player patrols.
Two players go and set up a sand off attack on the enemy base. One of them Usually has the quad damage.
I get the speed thing. Run into the enemy base, get the flag and run like hell. One of the stand off players follows me out. The other goes and hides somewhere near the enemy flag post to steal it as soon as it re-appears. mean while the patrol guy makes his way to the enemy base to take on the role of a stand off attacker.
7 Player is pretty similar to the 5 player one, but the extra human player is usally used in a sniping/camping role, while the extra computer player is used to help defend our base.
Although, both teams use the same tactics, it still gets really good and a lot different to a all out attack deathmatch.
