ShrinkerGun: COMPRESSOR

A shrink ray you can buy in the shop. Shoot anything to shrink it. Shoot it again to restore it.

v0.6.0: ScalerCore 0.6.0 under the hood. Loom's arms finally fit a shrunken body. Held forceGrabPoint items sit at eye height when shrunken instead of waist. Pair with ScalerCore 0.6.0 and REPOLib 4.0.2.

Enemies, valuables, items, players -- if you can hit it, you can shrink it.

What happens when you shrink stuff

Enemies get tiny, squeaky, and mostly harmless. They still chase you, but their damage and speed drop with their size. Their grab force goes to zero, so you can pick them up and throw them.

Valuables shrink for easy transport. No more struggling with oversized items through doorways. Shrink it and toss it in the cart. They stay small until they take damage, so carry them carefully.

Drop it too hard and it pops back to full size:

Players can shrink each other. Tiny players get squeaky voices, big anime eyes, and adjusted camera so it actually feels right. Walk under doors you'd normally crouch through. Take damage to pop back.

Carts, cart cannons, and cart lasers become pocketable when shrunken. Shrink one, press an inventory key, stash it. Pull it out later, still tiny. Shoot it again and it's full size on the ground.

Items shrink too. Grenades get smaller explosions. Orbs get smaller radius. Even doors. Why not.

Works great with cart mods

Already using ScaleInCart or SylhShrinkerCartPlus? The COMPRESSOR handles everything those don't: enemies, players, doors, stuff that hasn't reached the cart yet. They work fine together.

• Shrink a valuable before you pick it up, then carry it through tight corridors
• Shrink an enemy mid-chase and punt it across the room
• Shrink your friend for laughs (squeaky voice and everything)
• Shrink the extraction haul early so you're not fumbling at the truck
• Pocket a shrunken cart for later

Balance

It costs a weapon slot and uses ammo. Everything has counterplay:

Configuration

Hardcoded defaults:

Multiplayer

All players need ShrinkerGun and ScalerCore installed. Everything syncs over Photon RPCs, including late-join.

Known Issues

• Loom (Shadow) arms may look off while shrunken (cosmetic, attack distance still scales)
• Some untested enemy types may float or clip slightly while shrunken

Report bugs on the GitHub issues page.

Dependencies

• BepInEx 5 (5.4.2305+)
• REPOLib (4.0.2+)
• ScalerCore (0.6.0+)

Changelog

0.6.0

• Updated: Requires ScalerCore 0.6.0. Loom's arms finally track a shrunken body. Held forceGrabPoint items (guns, melee, batteries) sit at eye height when shrunken instead of waist. Big API expansion that lets other shrinker cart and persistent-shrink mods drop their reflection workarounds.
• Updated: Requires REPOLib 4.0.2 (customize menu fix, meta save backup).

0.5.2

• Updated: Requires ScalerCore 0.5.2 (fixes a KeyNotFoundException in GetBaseGrabStats that was breaking voice cancel on unshrink and level transitions, plus a non-host cleanup hole that was leaving voices stuck pitched).
• Updated: Description refreshed to mention v0.4 content (cosmetic boxes, vehicles).

0.5.1

• New: Cosmetic boxes shrink now. They sat outside the previous handler predicates (no ValuableObject, no ItemAttributes) so the gun just bounced off them.
• Fixed: Shrinking the new ItemVehicle while a player was sitting in it shrunk the colliders and grab point but left the visible mesh full-size. The game deparents the mesh from the vehicle root when occupied, so it no longer inherits the root scale. Then expanding made the mesh balloon to about 2.5× original because the next reparent had inflated its localScale to compensate for the shrunken parent. Vehicles shrink and grow normally now whether occupied or not.
• Fixed: Shrunken vehicles wouldn't turn. Throttle worked, so they'd accelerate in whatever direction they were facing and there was no way to steer. The game's mount check uses a hardcoded distance that doesn't scale with the vehicle, so on a small scooter the seated player could never finish "mounting" in the game's eyes and steering input stayed clamped to zero.
• Fixed: Shrunken Semiscooter (the regular one) had no inventory icon when pocketed (the small variant did). The icon renderer was looking for visuals under the vehicle root, but the regular scooter deparents its mesh and the bounds calc missed it. Renders correctly now.
• Fixed: You could pocket a shrunken vehicle while you were also shrunken. That was supposed to be blocked the same way shrunken carts are: fits in your pocket only if you're full-size.
• Fixed: Carts could vanish on the second shrink. The icon-generation path had an order-of-operations bug that NRE'd inside the game's icon coroutine, which itself moves the item to (-1000, -1000, -1000) for rendering and was leaving it there. Carts stay alive across as many shrink/unshrink cycles as you want.
• Improved: Shrunken vehicles (ItemVehicle, ValuableArcticSnowBike) now drive at proportionally lower top speed instead of full speed on a tiny chassis. Vehicles stay pocketable when small (and only when you're full-size).
• Updated: Requires ScalerCore 0.5.1.
• Updated: Requires REPOLib 4.0.1.

0.5.0

• Updated for R.E.P.O. v0.4: Rebuilt against the latest game release. 0.4.4 will not load on v0.4.
• Updated: Requires ScalerCore 0.5.0 (multiplayer fix: map collapse messages, sirens, and the truck cascade were running way too fast)
• Updated: Requires REPOLib 4.0.0.

0.4.4

• Fixed: Non-host clients could trigger scale/restore logic directly, causing desyncs
• Updated: Requires ScalerCore 0.4.4

0.4.3

• New: LevelCollapse setting (Chaos section). Shoot the map with the shrink gun. Auto = April 1st only, On = always, Off = never.
• Moved: ShrinkChallengeMode and all user-facing settings now live here
• Fixed: Map collapse audio respects master volume
• Fixed: Pocketed item icons no longer disappear after level transitions
• Fixed: Camera glitch effect fills the full screen while shrunken
• Improved: Pocketed items generate icons at runtime (no more embedded PNGs)
• Improved: Map collapse crush feels heavier (FOV slam, shake, and a brief hold before death)
• Improved: Map collapse enemies are slightly faster instead of comically fast
• Updated: Requires ScalerCore 0.4.3
