Shrinkinator

BepInEx mod for R.E.P.O. that adds a shop weapon: the Shrinkinator. A shot sprays green mist; anything in the cloud shrinks.

• Valuables shrink permanently (size and mass), down to a configurable minimum so they cannot vanish from stacking. Dollar value stays the same.
• Enemies and players shrink temporarily (20 seconds by default), then grow back. Shrunk players get a lower camera, smaller hitboxes, and shorter grab reach.
• Shrunk enemies are lighter and easier to grab (works like a strength upgrade: a short tug picks them up and briefly stuns). They are not hard-stunned by the ray itself.
• 6 charges via the vanilla battery (recharge at stations).
• Procedural retro ray-gun model (can be turned off in config).
• Multiplayer: Photon RPC. Every player in the lobby needs the mod.

Install

r2modman / Thunderstore Mod Manager (recommended), or manually:

1. BepInEx 5.4.21 (x64), launch the game once.
2. REPOLib 4.2.0+.
3. Put Shrinkinator.dll in BepInEx/plugins/.

The gun shows up in the shop (weapons), priced 1.5× the vanilla pistol (configurable).

.NET SDK 8+:

dotnet build -c Release
# bin/Release/netstandard2.1/Shrinkinator.dll

BepInEx/config/com.kimi.shrinkinator.cfg after first launch. Notable defaults:

Thunderstore / CI

Push to main builds the mod. If the repo secret THUNDERSTORE_TOKEN is set, the same workflow publishes a new version to Thunderstore (R.E.P.O. community, team Avariiiprime) when the version in Shrinkinator.csproj is new.

Create a Thunderstore service-account token (team settings → Service Accounts) and add it as THUNDERSTORE_TOKEN in GitHub → Settings → Secrets and variables → Actions.

Manual publish: Actions → Publish to Thunderstore → Run workflow.
