Impostors have the ability to call various sabotages, which create temporary problems that the Crew will need to resolve.

• Sabotages can be fixed by an Impostor
• All sabotages have a cooldown of 30 seconds
• Critical sabotages include a countdown which will cause an instant win for Impostors once it reaches zero

Sabotage Lights

Installing is simple, simply drop the plugin.jar into your /plugins/ directory as you would any other plugin and restart your server - /reload is also possible

Creating a Map
Once you have created the physical map (or as you are building it) you can use the in-game interactive map editor to create and edit a map, simply running /Impostor Map Edit [Id] will guide you through the required steps to create a map.

Note: You will first need to create a map via /Impostor Map Create [Name]

Creating a Game
Provided there is at least one map available, you can create a new game instance via /Impostor Create, this will open a game settings screen which you can re-open via /Impostor Edit, once enough players have joined your game and you are ready to start, simply click the Start Game button from within the game settings menu.

Note: The start button will not allow you to create a game if an existing game is already using the selected map, if the map is currently being edited, or if you do not have enough players (a minimum of 4 players is required)

Joining a Game
Running /Impostor Join will open a menu which lists all the currently available game lobbies, joining one of these will include you in the game once the lobby leader starts the game. (see above)

/Impostor Edit - Opens the edit game settings menu
/Impostor Join - Opens the view existing lobbies menu
/Impostor Leave - Leave your current lobby or game (if you are in a lobby or game)

The config.yml file contains two chat color fields for setting the general commands and feedback message colors.

Asteroids_Tick_Rate can be used to globally set the speed of asteroids in the clear asteroids task, smaller is faster, defaults to 2 ticks.

Adding Dev_Testing: true into the config allows games to start with any party size and removes the win condition for when impostor(s) outnumber crew. (useful for testing with <4 players)

Most of the plugin setup and configuration is managed in game, see Setup and Commands sections above for more information.
