Team Hold the flag.

there are 2 teams just like CTF and one flag point. first, they have to get the flag from the flag point. every 5 seconds they hold it (the team) makes a team score. If the flagholder dies the flag respawns at the flag point and the teams can re-cap the flag again.
OR the flag stays where the flagholder died died to pick it up again.

Hold the flag.

Same system as above but then invidual.

Infiltration.

Like CTF, but one team(blue) has to defend their flag and the other team(red) only has to cap and score. blue team gets 1 point every 5 seconds.
red team gets 20 points by capping and scoring.
NOTE: If the flag is capped makes the blue team out off score-system. that means that the blue team won't get points every 5 seconds when flag isn't at base.

i don't know if this is possible tough, it's a suggestion.

hope you like it.. atleast.. if you understand what i am saying here.

Note: if somebody already thought off these gametypes, it wasn't my idea to steal it. I just didn't read the whole thread here.

i am so sucky in thinking off gametypes :S
