I had a mess around on a demo of this today in the HMV store.
Unfortunately they weren't able to connect to the net as the connection speed was rubbish.
Seems like a good game though. I only player the tutorial bit so not a vast intake of content but it played well, had some neat features (like a supply crate where you can kneel down and stock up on ammo, etc...) the controls were also fairly intuitive and very responsive.
Pity I don't have a PS3 though
