One character doesn't make or break a game. Rochelle is just one of 4 characters you play while killing zombies. I don't know about you, but I don't give a damn what they say unless it's a special infected's name, "I'm down!" or "I'm gonna die!".
L4D2 is just a tad higher, although it lost many approval points from me because of melee weapons and defibs.
Melee weapons against few infected :D
Stand in a crowd of zombies in versus and chop away? No.
HURR DURR 2 DEFIBS IN ONE VERSUS ROUND.
What I hate about melee weapons is, when you melee with them (push zombies back), you get tired, but when you chop zombies (which takes more energy) you never loving get tired. How does that work? Pistols need a buff.
