1. Open it and select "Play" to start a new game.

2. You will join a game with other players, who may be either crewmates or impostors. Your goal as a crewmate is to complete all your tasks on the spaceship before the impostors can eliminate you.

3. As you move around the spaceship, you'll see various tasks to complete. Complete them by tapping on the task and following the instructions.

4. Be on the lookout for suspicious behavior from other players. If you see a player acting strangely or trying to follow and corner you, they may be an impostor.

5. If you believe you have found an impostor, you can call an emergency meeting by tapping on the emergency button in the middle of the screen. During the meeting, players can discuss who they think is the impostor and vote to eject them from the spaceship.

6. If you are an impostor, your goal is to eliminate all the crewmates before they can complete their tasks. You can do this by sabotaging the ship's systems or by killing crewmates when no one is watching.

7. Be careful not to get caught by other players. If another player sees you kill or sabotage something, they can report you to the other players, who can then vote to eject you from the spaceship.

8. The game ends when either all the impostors are eliminated or when all the crewmates complete their tasks.
