I played this game a couple years back on PC ad it is very reminiscent of Diablo 2 with a whole bunch of features that are easy to learn. There are 7 character classes, from your standard Paladin, Marauder, and Ranger. To you more technical cut-throat, Witch and Duellist. Each character starts at a different passive skill tree location but there is potential for a lot of customisation.
The Incredible Adventures of Van Helsing trilogy has gathered quite the following on PC, and seeing as the very first game of the trilogy was available on Games With Gold a few months back, it may interest you to know that, thanks to Neocore games, the second instalment in the series has launched on Xbox One.
