There are still nade launchers in black ops, however they arent a massive issue like MW2, because there is no Danger close + 1 man army bullshit
i prob get noobtubed a few times a night. happens in objective games more, tossing one on a flag in domination is pretty effective
I'm a noob-tuber, but generally only during objective type games. Something I think they messed up on is not allowing me to use Warlord with under barrel mounts. Because I can't throw a RDS on, I always go with SoH - faster noob-tubes is great!
