I actually haven't bought this game, yet. I was playing it at a friends the other day and I've got the urge to pick it up now. But I can't allow the purchase until money is flowing a little more freely. *sigh* Sod it!
Online Co-Operative Mode is still good fun like. I tried the Competitve side of things, in a Skirmish game, I think. I can't say I was fussed over it at all. I had a few games where our team done well, and a few where we didn't, but it just wasn't all that exciting to be a part of.
Playing a shooter online brings back memories of good ol' Return to Castle Wolfenstein. What a game that was. Loved the Tram map.
