Great game, the frontline system works well, keeping players moving. Roles are well devised with choice of weapons and equipment. There are some secret achevements which I accidentaly got one of, which is otherwise pretty hard to get i think(unfortunately, it's not to brag about), i'm not sure if the other one is similar but i got a funny one, not telling anyone more than that there. It looks like there could be some DLC(downloadable content)
The single player is cool, leading you on multiple and different missions as the 'Stray Dogs' a squad which makes more sense than the one man VS the rest of the world.
It gets a 4 star because there are some bugs like a floating box but it does look like it could be easily fixed, other that that it's great and i would highly recomend it.
