Sure. The texture's aren't awesome if you ask me. I hope you have a dedicated server or above average machine if you plan to host any games.
Character models are your default look, unless you can customize them? I haven't played but an hour or so before I had to get things done.
The zombies extension is pretty challenging, farthest I've gotten with a random group is 7 rounds.
I agree with Jwins, doesn't have the feel of a "realistic" shooter. Tons of run n gun. More arcade style and the hit box just feels....wrong. Head-shots aren't always registered even if you land them.
I found I get better performance if I'm not using the latest cat 10.10 drivers. (ATI only comment) However AMD was kind enough to release a hotfix for the 10.10 which included their morphological AA. That's a bit technical and problem wasn't needed to get my point across, but details are always nice.
I've been having some multi-player connection issues so far that aren't limited to myself. Game runs through Steam so I'm sure the high volume of use plus being a new product means we'll be hearing about an update/patch or quick fix soon.
So far I haven't been disappointed though. Single player is pretty intense. The lighting and environments are done very well.
I'd say give it a shot myself.
