================================================
MIMESIS
MIMESIS is a 4-player online co-op horror game where monsters imitate your friends. Gather anything of value and get back to the tram, never quite certain whether the person beside you is a real friend or a monster wearing their face.
Trust your friends. But doubt them.
Threats are scattered all through the building. Together with your friends you can push past the danger and haul your findings back safely. But don't forget: the person next to you might be a monster imitating a friend.
Beware the contaminated rain
The rain in this world is dangerous. Once night falls, the tram is the only shelter from it. You have to be back before midnight. Take on too much rain, and the next monster might be you.
Buy and upgrade your equipment
Collect enough and you can use the service station. Restore power to the dormant station, then buy and upgrade your equipment. Strong gear makes a real difference to survival. It isn't free, of course.
