Scratch that, I missed a paragraph in OP's post about the assassin. Definitely not SpaceTeam and more likely Among Us.

Give SpaceTeam a try anyway. You have to love a game that bills itself as a "cooperative shouting game."

Spaceteam also exists as a physical card game, the mechanics seem to be a bit different from the app (not sure which one of them was released first) but is still lots of fun and shouting.
