a mod called colors, which will feature full out gangwars bettween 2 differant gangs in a cs-style rule set.
kill everyone to win. (with the bomb and hostages aside)
there will be 2 to 3 rounds, then the match will start over (if pre-set server side, depending if its a red-vs-blue style server or strictly gangwar)
in gangwar each gang must have 1-3 colors (3 being the most colors usable)
e.x.
Red & Grey ([KFC])
Blue and Black (=AA=)
Blue ([uLK])
idk what other colors, but i know those two gangs associate themselves with those colors already
you CAN have two gangs with the same colors, but its not good practice and might start rivalries (*GASP!*..lol)
