Anyone played this yet? I've never played GTA, but from what I've seen, this appears pretty similar.
You go around picking up contracts from different factions in north korea fighting NKs and picking up weapons and vehicles along the way. The game play is a little too easy to be a good shooter, but you get to blow sh!t up and can pilot any vehicle that moves. (Helicopters, tanks, scout vehicles and civilian transports.)
The game isn't very linear, which in my eyes ups the replay value. When you're not tied into a contract, you can drive all over the place looking for each member of the "deck of 52" or just random fighting in general.
The Russian Mafia gives you access to support items that can be dropped into just about anywhere, and you unlock new support items as you progress. So far, I've unlocked a couple different vehicles and some really cool air and artillery support options.
I'd give this game a 8 or 8.5 if you're thinking about buying it.
