Ever play a game of hide-and-seek in your childhood? Maybe with a mix of tag thrown in to spice things up? What if you upped the ante a little and changed into a horrific sea monster and your four friends have to escape a decrepit sea fortress or face certain doom? No? Well, Monstrum II has you sorted if you had an itch for such a highly specific game of tag. Taking place on a 1970s era sea fortress, take up the mantle of a deadly oceanic monstrosity or as one of four prisoners who are stuck on this grotesque experiment.
