For instance, if team damage = 1; you damage teammates the same as enemies.
If team damage = 0, you cannot damage teammates, at all.
If team damage = -1, you can only damage teammates.
Also, the team damage variable should effect deployables, so teammates cannot destroy your defenses.
The team damage variable should be specific to each zone, for instance, team damage can be 0 in CTF, 1 in Arena, and -1 in Duel zones.
But wait, there's more!
Team damage variables could also be specific to clients... For instance, an admin could enable team damage for specific players so they can remove deployables placed by scumbags.
