🔪 MRT ImposterUs
Among Us inside Minecraft. Tasks to finish, sabotages to repair, vents to vanish into, bodies to report and meetings to lie in. No client mods: it works with any vanilla player.
✨ Features
🎭 Secret roles
- Crewmates finish their tasks or vote the impostors out.
- Impostors kill, sabotage and hide in vents until they match the crew in number.
- Optional sheriff (one shot: miss and you die) and engineer (can use the vents).
🧩 14 task minigames
Each with its own interface, not a block to click: fix wiring, swipe card, download data, align engine, fuel, asteroids, keypad, medbay scan, garbage, canisters, O2 filter, Simon sequence, calibrate distributor, breakers.
🚨 5 sabotages
- Lights — the crew can barely see until the panel is fixed
- Communications — task progress disappears
- Reactor and Oxygen — a deadly countdown: repair it or the impostors win
- Doors — seal the passages chosen during setup
🗳️ Meetings
Body reports and a multi-block emergency button, assigned seats at the table, discussion, live voting and ejection with role reveal.
👻 Ghosts
The dead keep doing their tasks, fly invisible to the living, chat among themselves and can haunt the living.
🕵️ Anonymity
Suit colours, hidden name tags and masked skins during the match.
📊 Scoreboards
A built-in sidebar for every situation (hub, waiting, countdown, match, meeting, ghost, ending). It is personal: your role and kill cooldown are shown only to you.
🛠️ Setup without touching files
A setup GUI and a step-by-step chat guide with clickable commands; markers in the map visible only to the editor; every match rule can be overridden per arena.
