It's no big deal, but it does make distinguishing your foes a little simpler. The re-designed menu systems are really nice to look at, too, are easy to navigate and make starting and joining games a cinch. Game modes comprise of old faves, such as capture the flag and deathmatch, plus capture and hold maps, which are pretty self-explanatory. Bounty game types are like deathmatches, only you are given one specific target. Kill a non-sanctioned target and you lose points.
Hunters is a bit crappy - simply deathmatch with more running around, but there is a team version.
In Rabbit games, players vie for possession of one flag. The player to hold the flag for the longest time wins. Last up is Siege - my favourite. Here, two teams battle it out over one switch. After the clock stops, or the map is conquered, the teams are reversed.
