Among Us first launched for iOS and Android in June 2018, followed by PC via Steam in November 2018. A Switch version launched earlier this week, and the PC version was made available via the Microsoft Store and Xbox Game Pass for PC today.
Here is an overview of the game, via the Microsoft Store:
Play with four-to-10 players online or via local Wi-Fi as you attempt to prepare your spaceship for departure, but beware as one or more random players among the Crew are Impostors bent on killing everyone!
Originally created as a party game, we recommend playing with friends at a LAN party or online using voice chat. Enjoy cross-platform play between mobile and PC.
