Trust in Play, "The Red Solstice can be played with up to eight people in a top down view as you control your marine. The eight of you will have to coordinate as a squad if you intend on surviving a mission or at the very least stick together. Creatures of some sort will be throwing themselves at you progressively getting stronger and stronger by waves. In the beginning you’ll have various dinky parasites run face first into your bullets. Then after 30 minutes or so you’ll end up dealing with giant behemoth creatures that will smash your face in with a wrecking ball. Over time the difficulty ramps up as you level up your marine getting stronger and stronger."
