In addition to the real time Skyrim-like looting system where you can get attacked, there is a XP system as well. The demo did not really get into depth with story. It plays like a basic zombie action game like Resident Evil 4 if it was First Person: the controls are precise and the game is sort of on rails with closed corridors, but still has areas to explore which hopefully the developers will work on i.e. collector’s items/weapons.
