The visuals are a little disappointing, but I just watched a 9 minute video on youtube of the beta and it looks like a lot of fun. A solid frame-rate with the amount of action going on, on-screen, will be far more important.
I'm amazed how similar the game looks to COD. I know the studio is founded by ex-COD developers, but you'd think that starting from scratch the visuals would have looked a bit different.
