I imagine there is no shortage of players online over the last 24 hours giving Call of Duty Black Ops a real work out. However, if your looking to game against some unique individuals then you should check out this Community Playdate that GhostCatfish5 posted about at the Xbox Live Community Team Blog:
On Wednesday, November 10, our Community Playdate will be with site members from WeTheGamerz.com, the site that’s for the people, and by the people. They’ll be on Xbox LIVE from 8-11 PM ET playing Call of Duty: Black Ops. Check out their gamertags and join them!
Sounds like they are just asking to get schooled a little bit at Black Ops – are you up for going against them for a few hours?
