Well, I hate to bombard everyone with so much Portal 2 news, but I doubt anyone really minds. The follow-up to Valve’s critically acclaimed title hits in February 2011, and in addition to having a more robust and lengthy campaign, it’s also going to add a new layer of replay value with co-op missions.

Honestly, I’ve been wondering how a co-op Portal game would work for several months now, as I’m sure many of you have. Well, wonder no longer, because Valve has provided a (very) brief trailer for Portal 2 co-op to give a glimpse of how it’s all going to work.

Also, I call the short fat robot buddy. I’ll fight you for him.
