Become The Monster

Turns one player per run into a controllable enemy instead of the usual robot. You keep moving and aiming the way you always do — you just look like, move like, and attack like the monster instead.

How it works

• At the start of a run, one player (roughly 1 in every 5) is secretly turned into a random enemy. Everyone gets a reveal showing who became what.
• Each form has its own attack, movement speed, and health, modeled after how that enemy actually behaves in the base game.
• Some forms have a second ability on right-click in addition to their main left-click attack.
• If your monster "dies," you don't drop a head and sit out — you get a quick death effect and come right back as a freshly rolled form. No two forms in a row repeat.
• Camera is third-person, positioned and scaled to whichever monster's body you're currently wearing.

Current roster

Gnome, Bang, Runner, Duck, Bowtie, Robe, Beamer, Floater, Spinny, Slow Walker, Birthday Boy, Hidden.

Notes

• This is a from-scratch reimplementation of each monster's attack/feel for player control — it does not modify or redistribute any of the base game's own files.
• Built and tested against game version v0.4.4.3.

Installation

Install with r2modman / the Thunderstore Mod Manager like any other BepInEx mod, or drop the DLL into BepInEx/plugins/ manually.

Changelog

1.1.0

• Possessed players who "die" now respawn immediately as a new random form instead of dropping a human head and sitting out — no repeats back-to-back.
• Reworked the camera to third-person, scaled per monster instead of a fixed first-person placement, fixing repeated cases of the camera clipping into the model.
• Per-monster health now pulled from each enemy's own real values instead of a flat default.
• Fixed several attack animations/visuals not playing (laser tracer shader, Hunter's aim windup, Beamer's real laser beam effect, walk animation not playing at all).
• Fixed animator "moving" state suppressing attack animations when attacking while still walking.
• Fixed several monsters' borrowed visual silently detaching from the player on spawn (caused by the base game's own enemy setup reparenting itself), which was the root cause behind a few forms never visually following the player at all.
• Elsa now starts calm/small like the real thing and only turns feral after being ignored or hit, instead of always spawning already transformed.
• Birthday Boy's balloon now uses the real balloon prop instead of a placeholder shape.
• Added a Force Field secondary ability to Floater.
• Trimmed the roster to the forms that are in good shape; a few are held back for further work.

1.0.0

• Initial release.
