Ghost Master is a strategy game with puzzle elements that allows you to play the bad guy. Your goal, as the Ghost Master, is to recruit and train a team of ghosts and cause all mortals to flee the area in fear. To do that you'll have to complete a number of missions in and around the Gravenville area.
Painkiller is the fast-paced firs-person shooter. As a tough, strong-willed man trapped in Purgatory, you're tasked with killing Lucifer's generals before you can ascend into Heaven. Between you and your goal stand uncountable hordes of enemies. Lucky for you you've got a unique arsenal of weapons at your disposal.
