My Night Job
Black night, an abandoned mansion and a bunch of monsters. Sounds like the perfect job. Players will have to use a a variety of weapons to save their skin and master the challenge of leading survivors to safety, while also defending the building from invaders. They can use more than 60 weapons, from vases and floor lamps to chainsaws, shotguns and ginormous hammers. If the monsters thrash too many rooms or the player's health bar runs out, only an entry in the highscore list will remain of you. REST IN PEACE!
Fast-paced, challenging action, hunting for the top spot in the highscore list, and an 80s horror movie setting - tons of fun and bizarre humor!
