DO NOT BUY THIS GAME. RENT IT.
It's fun to go around on killing sprees and to do the missions but this is the kind of game you would just want to play once just to finish the story.
Some of the trophies are hard to get because the number you have to hit is HUGE so you would have to use a lot of roaming time to kill over 53, 000 people and some of the events are nearly impossible to get gold medals because the controls are a bit faulty.
I played it on normal difficulty and some missions are ridiculously hard so I can imagine how the game is on the actual hard difficulty.
It's not a bad game at all but it gets boring doing the same things over and over again, which is basically either running around and killing people, consuming people or hopping into tanks.
Also, the hunters are a rip off of the lickers from Resident Evil and, being a Resident Evil fangirl, that made me grrrrrr.
I'd agree. It can be an entertaining game, but it has too many issues to be a good game.
