Single player(3*), first it is very short, maybe 2-3 hours, the story is good and a lot of action but way to short. They have said there may be a DLC for the story so hopefully they might add a couple more hours to that. You do get a wide veriaty of objectives in the single player which is good and your team mates do help.
To sum it up the story is good just too short.
Multiplayer(4*), since release I have had a red bar connection but not always lagging, the vehicles are good but they do get destroyed quite easy. An average choose of weapons and some good equipment, the controls on vehicles is easy. Would like to have seen destructive enviorments but it doesn't ruin the online for me, what does is the connection which is why I have stopped playing and gone back to medal of honor.
I was thinking of selling but I'm going to wait awhile see if they patch the connection problems and see where to go from there.
I would say buy pre owned or wait for the price to drop as its deffently not worth £40.
