One of the games of all time.

This game is definitely worth the $5 it asks. It may be free on mobile but its just a lot better on pc. As it is only $5, it is most certainly a steal. This is how the game works.

Crewmates (Innocent):
-complete randomly assigned tasks
-some tasks are visual, and your crew can see you do them
-when a body is found, meet and discuss evidence
-vote whoever is deemed too suspicious

Imposter (Traitor):
-fake tasks to gain crewmates trust
-sabotage O2, lights, reactor, or comms to cripple the crew
-kill crew until there is an equal amount of living crew and imposters
-use vents to escape suspicous situations

This game is quite easy to learn, so there isn't much learning curve. Just be aware that the servers are quite garbage, and when you are trying to join a friend's server the game just won't let you in. I'm sure that this is soon to change due to the popularity of the game.
