Got this a few days ago. Very pretty, smooth gameplay, and fun, if you like Unreal, it's worth a go, even though the Flak Cannon still uses the nerfed alt-shot.
My only complaint is that lack of content to be honest. There's surprisingly few maps that come with the game (though that will increase with the user-editing base that Unreal has) and the campaign is...short, and suffers from 'Sequel Syndrome', I won't ruin the game by saying more than that, however.
All in all, a good successor to Unreal Tourneys of the past, not a waste of money, but I think this was, despite the claims, totally oriented to online play, which I'm not a huge fan of, I won't be getting any more if it carries on in this direction.
