Good luck even maiet couldnt get a second version going because despite the bugs from gunz the duel thats what made gunz the duel good and which is why gunz the duel 2 sucked
Best of luck
GunZ 2 was like MapleStory 2: same graphical style, completely different game. Hence why it failed. It was just a new game with the looks of the original, but nowhere close to the same feels.
