Version: 1.2.7

Adds the Among-Us-style Impostor mode to REPO.

Mod required on all clients for full features. ⚠️

Made with love over the past months — tips are greatly appreciated! ❤️

Features

• Host-configurable gameplay options:
• Kill cooldown, Kill range, Emergency meetings per player, Meeting cooldown, Vote duration.
• Hotkeys (configurable):
• Report (default R)
• Meeting (default E)
• Kill (default K)
• Host-only lobby UI to change settings; changes are synced to clients for that round.
• End-of-round popup + automatic transition to Arena.
• Voting & emergency meeting UI integrated with game flow.

Installation

Manual (download)

• Download the mod.zip.
• Extract the ZIP and copy the BepInEx/plugins/ImpostorMod/ folder into your game install folder (where BepInEx is).
• Start the game.

r2modman (recommended)

• Open r2modman and select the REPO game profile and search for the Impostor mod (Impostor_Mod_Among_Us_Style).
• Launch the game through r2modman.

Configuration

Defaults are provided via BepInEx config and can be overridden either in the config file or via the in-lobby host UI:

Some of them:

• Gameplay -> KillCooldownSeconds — seconds between kills
• Gameplay -> KillRangeSeconds — kill distance (meters)
• Gameplay -> VoteTimerSeconds — vote duration (seconds)
• Gameplay -> EmergencyMeetingsPerPlayer — meetings per player

Usage

• Host: open Lobby → Impostor Mod Settings (right side). Only the host can change settings; client sliders are shown but disabled. Host changes push to room properties and apply for that round.
• In-game hotkeys (defaults): R = Report, E = Emergency Meeting, K = Kill. These are configurable via the BepInEx config.
• When a round ends the mod shows an end-of-round popup and after a short delay transitions players back to the Arena.
