EnemyDrops

Enemy Drops

Make monsters drop items when they die — fully configurable and host-only. Native BepInEx mod.

### 👥 Multiplayer: Only Host Needed (Clients Optional) Your friends do NOT need to install this mod to join and play! * For Clients WITHOUT the mod (Vanilla): * ✅ 100% full gameplay (enemy drops, item pickup, and item preservation between levels). * ℹ️ Dropped items look like regular items, without the dark tint or reddish glow. * For Clients WITH the mod (Enhanced): * ✅ Full gameplay + the dark tint and pulsating reddish glow on enemy drops.

Inspired by the original REPO Enemy Drops mod by ImVertro. This version is a fully native BepInEx implementation for users who prefer not to use MelonLoader, with additional usability improvements.

What's new

• New items: Human Gun, Human Adventure Cable and Recharge Orb from the Sunstone update can now drop.
• Balanced by shop price: cheap items drop from easy monsters, expensive ones from hard monsters.
• Live weights: drop weights changed in-game apply to the very next drop.
• New switches: Enabled, ResetWeightsToDefault and ZeroAllWeights.
• Glow for clients with the mod: players who also have the mod see the glow on drops.

Features

• Item Preservation: Option to keep items secured in the truck or inventory across subsequent levels.
• Preservation Limit: Configurable cap on the maximum number of enemy-dropped items that can be preserved simultaneously (default: 10).

• 100% native BepInEx implementation.

Requirements

• BepInEx Pack for R.E.P.O.

Installation

1. Install the latest BepInEx Pack.
2. Place EnemyDrops.dll into your BepInEx/plugins folder.
3. Launch the game once — the configuration file will be generated automatically inside BepInEx/config.

How to Use

1. Install the mod on the host (friends do not need it).
2. Play. Monsters drop items when they die; stronger monsters drop pricier items.
3. Tune the weights in the in-game config menu or in osmarbriones.EnemyDrops.cfg. Items are listed by their game names (e.g. Item Gun Revolver is the Human Gun).

Configuration

All settings are controlled through the generated file: osmarbriones.EnemyDrops.cfg located in BepInEx/config.

General Settings

• Enabled (Default: true): Turns the mod off entirely. When false, enemies drop nothing.
• ResetWeightsToDefault (Default: false): Set to true (e.g. from the in-game config menu) to restore every drop weight, for all three monster tiers, to its default. The switch turns itself off afterwards.
• ZeroAllWeights (Default: false): Set to true to set every drop weight to 0, so you can then enable only the items you want. The switch turns itself off afterwards.
• MaxDropsPerLevel (Default: 200): Maximum number of items that can drop in a single level.
• PreserveItemsBetweenLevels (Default: false): When enabled (true), enemy-dropped items that players carry to safety inside the truck or keep in their inventory will persist into future levels and be saved with your run.
• MaxPreservedItems (Default: 10): Maximum number of enemy-dropped items that can be preserved simultaneously. Standard shop-purchased items do not count toward this limit.

How Item Preservation Works

When PreserveItemsBetweenLevels is enabled (true), you can save enemy drops across levels and into your saved game:

• Securing items: An item is considered secured if it is inside the truck room, held/grabbed by any player, stored in a player's inventory slot, or placed near the truck entrance (within 8 meters).
• Preservation cap (MaxPreservedItems): You can keep up to the configured limit (default: 10) of enemy drops active at the same time. If more secured enemy drops are brought than the cap allows, items up to the limit are preserved and any surplus is discarded.
• Shop items are exempt: Items purchased from the shop do not count toward this limit.
• Dynamic slot recycling: When you consume (e.g. syringe, medkit) or lose a preserved item, its slot is freed up automatically so new enemy drops can take its place.
• Host-authoritative: Only the host needs this enabled. Items secured by any player (host or connected clients) are properly evaluated and saved.

Difficulty-Based Drop Tables

The .cfg file includes three difficulty sections:

[Easy Monsters (Elsa for example)]
[Med. Monsters (Chef for example)]
[Hard Monsters (Robe for example)]

Each section contains entries like:

## Weight for "Item Gun Shotgun" on medium monsters. (range 0..12)
# Setting type: Int32
# Default value: 2
# Acceptable value range: From 0 to 12
Item Gun Shotgun = 2

How weights work

• A value of 0 means the item will not drop for that monster difficulty.
• Higher numbers increase the probability of the item being selected when a monster
