Megaten Online Client Modification

A little bit strange game, and as for me not so dynamic as e.g. Martial Empire or even Requiem. Nevertheless, you can use Ollydbg for disassembling this game. At this moment I don't know what can be done and what can we change/modify, because I've played only 30 min. But multiclient is piece of cake.

P.S. This game uses GameBryo Element engine like Requiem.
