Okay, i have this game and will explain why its so good because i was having a chat with old snake (cant remember PSN)
Its a sandbox game, the campaign is quite shite yeah i admit, but online is well good. Its pretty tactical aswell, on the oasis level you have to be quick and one step ahead.
on harvest day level you need to be more sneaking and rely on your team to cause havoc.
every level is different, also if you get bored of being assault, you can snipe. you always have the option of being support which allows you to heal your team mates, each class allows you to do different things.
Im still unlocking some things, not sure on what to unlock.
C4 or Anti-tank mines.
