Game seems abandoned, I tried to play it but it'd bug out if you clicked off screen and if you dared put it into full screen it'd just completely crash. Its a shame.. I played it when it was Bloodymare in early 2000s, was hoping for a nostalgia trip.

The game that promised to be the darkest and bloodiest MMO ever made now hangs on by a single nerve ending.

fun game, even still today. love the horror-themed graphics and skills and abilities are interesting and unique. weapon and gear system is a bit tricky to grasp at first but you basically want to enchant your items as soon and as much as possible, especially accessories, for magic damage at least as i'm running a templar and my accessories are giving me +6 magic damage each. overall would recommend to anyone looking for a hidden gem in the dark fantasy category of mmorpgs.
