Awful.
I've been out of these types of games for 10+ years but now my son is older and has started playing them I gave it a try.
It's a terrible game. The graphics, compared to CoD, are weird surreal and look like graphics in an age when a lot of games are getting better at capturing the life like it's to a poor standard.
The guns, again when compared to CoD, don't 'feel' right, you never quite get the feel of it shooting a gun it is so obviously a game rendering of shooting a gun.
Then there are a myriad of other little problems but all in all in an age of games getting better, more refined, more "life like" in what they are trying to create it just feels a twitchy mess that would have been suited for about 15 years ago when I used to play (and even then it wouldn't match up to a lot of those games.)
