I got this the other week and I'm loving it at the moment. Makes a nice alternative to TF2 without being too different. I didn't get it on release as I thought it was too vehicle based which I don't like. However, that doesn't seem to be the case which is a win in my book.
I'm still learning the game and getting used to the maps, so I've got a long way to go skill wise. I'm also used to the more in your face, fast paced FPSs like TF2 and Unreal Tournament, so I've got that to adjust to too.
I've been playing a bit on the hardcore TFU server with an OcUK tag on so some of you may have seen me about. I didn't use to like hardcore mode at first, but once I got used to it, I think I prefer it. I'll have bit more time to play over the weekend and you may even see me on vent if I can be bothered to plug in my headset!
