Initially, the game was streamed by players in South Korea, Brazil, and other countries before it caught on this Spring in the English-speaking world. Since then, Among Us has had a rocket ship-like trajectory toward popularity, even earning its own Nintendo Switch port this month.
The rules of the game are pretty simple. There are two teams, the alien imposter(s) and the humans. The humans are tasked with making sure their space shuttle launches successfully by completing all of the objectives and finding imposters. The imposter on the other hand, must ensure that the ship doesn't take off by means of sabotage or killing all of the real crew members without being discovered.
Where Among Us shows its real charm is in the process of deduction. The act of deciding who's an imposter and who's an ally is carried out via in-game "meetings" which are triggered when a body is found. This facet of the game requires players to actually speak to one another through a microphone.
Among us is only playable online with other humans (4-10 people), meaning the social interaction is baked in, you're forced to interact with both teammates and adversaries using real, spoken, human words – a luxury in a time where most people are living their lives intentionally avoiding contact with others.
In part due to the social aspect, Among Us packages the fun of playing a board game with friends into a format that, despite falling short of actually replacing human closeness, acts as a valuable sit-in for activities that (because of COVID-19) could potentially endanger ourselves and others.
