the competitive multiplayer is obtuse and kinda bad. it's basically halo but you bring in your weapons and abilities so the balance and pace is off. for example, if you throw a grenade and die, you down have another grenade when you respawn. it's on the same cool down timer. ammo doesn't refill, so if you died without ammo, you need to go find an ammo cache upon respawn. and you need to bring weapon types (sniper rifles, shotguns) with you because you don't find weapons on the map. I'm assuming this is what pvp modes in mmos are like. or pvp in borderlands, if that exists.
