In The Guest, players will represent the crew of the extrasolar ship Beagle, which is attacked by a strange parasite that lodges itself in people`s brains, controlling their will. A hidden role game in which the tension is real in each vote. Some players will represent infected crew members who try to infect or kill the rest, and others will be healthy crew members who try to safely reach the Aurora space station. The objective of each team is to kill the members of the opposing team, but no one knows who the crew members infected by the hosts are. But be very careful, a third side could appear if someone loses their mind.
