Cart Compressor — Cart Crunch

A standalone R.E.P.O. upgrade that makes cart hauling a personal specialization. Buy the cereal box, eat it, and compress cargo when you handle a cart.

Public beta: built against R.E.P.O. v0.5.1. Multiplayer synchronization is implemented but has not received a full multiplayer playtest. Please report issues with versions and reproduction steps; redact personal details from logs.

Three personal levels

Each box has a regular price of at least $15,000; vanilla purchase scaling may increase it. The shop robot's successful discount uses the normal game rules and can reduce the price below $15,000. A fourth use is blocked without consuming the box.

• Only the player who eats the box receives the upgrade. Buying it does not upgrade the team.
• Parked carts retain compression while their owner is alive and connected.
• An unupgraded player grabbing or physically colliding with the cart cancels compression.
• Multiple qualified handlers use the lowest participating level.
• Cargo returns to normal size after leaving the cart. Mass, value and durability are unchanged.
• Only ordinary valuables are supported. Shop items, players, enemies, heads and mountable vehicles are excluded.

Installation

Use r2modman or Thunderstore Mod Manager. Requires BepInExPack 5.4.2305 and REPOLib 4.3.0.

No ShrinkCart, ScaleInCart, ScalerCore or REPOConfig required. All players need the same version of Cart Compressor and REPOLib. Disable competing cart-scaling mods.

Manual installation: put CartCompressor.dll in BepInEx/plugins/CartCompressor/. Remove older duplicate copies first and restart the game.

Appearance and configuration

Look for CART COMPRESSOR: a vanilla-shaped yellow cereal box with CART CRUNCH artwork, cyan cubes and a cart. Shop stock is random. The public build has no item-spawn hotkey.

Configuration: BepInEx/config/Local.CartCompressor.cfg. The enable switch is host-controlled. REPOConfig is optional. Old save IDs are preserved; an existing single upgrade becomes level I.

Known limitations

Physical touch requires an actual Unity collision. The host checks carts every 0.1 seconds and sends reliable snapshots every 0.5 seconds. Late joining, host migration and packed-cart expansion need more multiplayer testing. Do not combine with other mods that resize the same valuables.

Development

Requires .NET SDK 8+ and .NET 8 runtime for tests, plus your own game installation and REPOLib DLL. Game assemblies are not distributed.

./build.ps1 -GameDir 'PATH/TO/REPO' -RepolibPath 'PATH/TO/REPOLib.dll'

The build runs 23 rule tests, checks five Harmony targets, discount compatibility and embedded artwork, and creates a Thunderstore ZIP in dist/. It does not install into the game. Pure rule tests can also run without game assemblies using dotnet test tests/CartCompressor.Tests.csproj -c Release.

Съедаемое улучшение телеги, три уровня: 76,67% → 70,83% → 65% размера. Цена от 15 000. Работает персонально; игрок без улучшения снимает сжатие при захвате или физическом касании телеги. Нужна только REPOLib поверх BepInEx. Это бета, полная проверка мультиплеера ещё не выполнена.
