A shrink ray for R.E.P.O. Shoot anything to shrink it. Shoot it again to restore it.
Enemies, valuables, items, players -- if you can hit it, you can shrink it.
Enemies get tiny, squeaky, and mostly harmless. Their damage scales with their size (40% at default shrink), they slow down, and their grab force goes to zero. That means you can pick them up. With your bare hands. And throw them at a wall. Or at your friends. A shrunken Huntsman is just a very angry football.
Valuables shrink down for easy transport. No more wedging that oversized painting through a doorway -- just zap it and toss it in the cart. Shrunken valuables stay small until they take damage (drop them too hard and they pop back to full size). They're briefly invulnerable after shrinking, so the scale change itself won't break anything.
Players can shrink each other. Tiny players get squeaky voices, big anime eyes, faster animations, and adjusted camera/collision so it actually feels right. Walk under doors you'd normally have to crouch through. Take damage to pop back, or press F10 to manually restore.
Carts become pocketable when shrunken. Shrink a cart and press an inventory key to stash it. Pull it out later and it's still tiny. Restore it (shoot again or let it expire) and it goes back to full size on the ground.
Items shrink too. Grenades get smaller explosions. Orbs get smaller radius. The gun itself can be shrunk by another player's shot (but won't shrink itself).
Shrinker cart mods like ScaleInCart and SylhShrinkerCartPlus are great for automatic loot management. The COMPRESSOR is a different flavor -- an active tool that gives you direct control, and works on more than just valuables. They pair well together.
If you use a shrinker cart for fitting loot into the cart, the COMPRESSOR handles the rest: tiny enemies, shrunken players, scale control over anything you can shoot.
Scaling behavior is built into the gun — it uses hardcoded ScaleOptions values tuned for the best gameplay feel:
| Behavior | Value | Notes |
|---|---|---|
| Scale factor | 40% | Objects shrink to 40% of original size |
| Enemy duration | 120s | Enemies auto-restore after 2 minutes |
| Valuable duration | Permanent | Stay shrunken until damaged or round ends |
| Item duration | 300s | Items auto-restore after 5 minutes |
| Player duration | Permanent | Stay shrunken until bonked or F10 |
| Enemy damage | 40% | Shrunken enemies deal reduced damage (scales with size) |
| Enemy speed | 65% | Shrunken enemies move slower |
ScalerCore has one user-facing setting in ScalerCore.cfg:
| Setting | Default | What it does |
|---|---|---|
| ShrinkChallengeMode | false | Players start shrunken. Guns temporarily grow you; damage shrinks you back. |
Works in multiplayer. All players need both ShrinkerGun and ScalerCore installed. Scaling state is synced via Photon RPCs. Players joining mid-game will see the correct sizes for everything that's already been shrunk.
