I had a quick blast last night, can't really judge it on one and a bit levels but it seemed like a decent enough game, the kill cams are obviously great fun.
There's demo on the PS Store so give it a try ("Sniper Elite" difficulty is the way to play this game); also you pretty much can buy it new for less than £30 so I think it's absolutely worth of consideration.
Have to agree, just got this game and can hardly put it down to play Max Payne 3. People have complained about some animation in your character not being solid, but when you aim down the scope it becomes an incredible game with very few shortfalls.
At under £30 it is almost a sure fire purchase for content to price ratio.
