Yeah I played this for a couple of hours last night. Initially I didn't think much to it but by the time I turned it off my opinion had changed. It's a cross between Left 4 Dead and Sniper Elite. The controls and UI are similar to Sniper Elite as it is the same developers. Visually it's nothing special but I had a lot of fun playing it. As it's a trilogy it's all 3 PC games in one so there's a lot to get through I reckon. I bet coop is pretty cool but Im playing the solo story mode. Im glad I don't regret buying it 
May the NFOrce be with you always.
