theres a couple ways they can do friendly fire in an MMOFPS:
1.)Friendly fire hits teammates for 50% (or less mabee) damage.
Automatic kick (back to city?) for 3 TKs inside 1 minute.
2.)Depending on how many GMs are going to be online...
Rsport someone for TK, GM observes them annonymously for a bit and decides whether they need a spanking or not
vote system = useless and very abuseable
3. idk im sure theres more
