Among Us has been updated to version 2021.3.13, which adds along other things the airship map.
Here are the full patch notes:
- The 4th map, and the biggest one yet
- New tasks including jewel polishing, emptying trash (wow fun), and more
- The ability to pick the room you start in
- All new areas to explore (or get murdered in)
- Improved mobility with ladders and moving platforms
- New free hats including a heart pin, angry eyebrows, unicorn head, rubber glove, and more!
- Inspired by our other game, The Henry Stickmin Collection
