There really isn’t anything else I can say more about Portal 2 that I haven’t already said before. Portal 2 is going to be beyond awesome and with the inclusion of a co-op game mode, its going to be EPIC. This is the extended trailer from PAX 2010 that shows off more of what to expect from co-op mode in Portal 2. It’s definitely going to be fun.
