i have played the DC sub. mode and its as Razon said so yea
An bomba_Twist Registration is'nt hard to do i have tried doing it before you just need those damn registration numbers wich is going to be hard to find
like i said, i know in the dc version its different, but its not me, its korean that made it like that, whenever i click sub mode, it goes as drop bomb. im not saying you guys are wrong, im just saying i think korean made a mistake. and yes registration is easy, just those fricken residential keys.
