It's a great game.
Fun game-play, various amounts of equipment including gun add-ons, masks, hats, camouflage, and different vest types. A good amount of maps, that vary from cities to jungles, to even snow, that vary on good hiding places etc..
Unfortunately though, the game is infested with hackers and nerds that spend $100's of dollars on the game. Nexon offers unrealistic advantages to people who buy NX. Especially with the release of Specialists who use guns such as Mini-Guns, Flame Throwers, Grenade Launchers, Air Support, and unrealistic speed advantages.
It's ironic that they're against hackers, yet they offer 'hacks' aka Specialists.
Anyways, it's worth a shot to get your own opinion on the game.
PM for my IGN name and I'll give you a tour. :P
