A few friends of mine play this game so I thought I'd join them and see what's hackable. MHS has no problem attaching when in Restricted Mode, however without Restricted Mode the game will close itself. I'll post any addresses I find once I get time to play it.
Anybody else interested in hacking it? It is a basic MMORPG, a lot like World of Warcraft except it is free (And everything looks much less "Warcrafty").
