--- title: Casualties Unknown Skins: How to Install and Change Them description: Which skin mod to use, how to install skins and how they sync in multiplayer. url: https://casualtieswiki.wiki/mods/skins/ --- Mods # Casualties Unknown skins From download to wearing a skin - 1 **Install the skin changer**Its files go in BepInEx/plugins - 2 **Download a skin**A folder holding a body sprite and more - 3 **Put it in CustomSprites**Folders are named 1 to 9 - 4 **Rename it to a free slot number** - 5 **Press the matching numpad key in game** _Steps shown in Meow's multiplayer skin guide (22 May 2026) and the sprite replacer's Nexus page._ **Short answer:** Casualties Unknown has no built-in skin picker for custom art. Skins come from a mod, usually **Player sprite replacer** or **Multiplayer Sprite Replacer**. Drop a skin into a numbered `CustomSprites` folder, then press the matching numpad key in game. confirmed You need [BepInEx working](https://casualtieswiki.wiki/mods/how-to-install-mods/) first. A skin mod only changes how your character looks and has no effect on game rules. ## Which Casualties Unknown skin mod should you use? These are the main options, with Nexus figures from 9 November 2026. confirmed | Mod | Best for | Downloads | Notes | | --- | --- | --- | --- | | [Multiplayer Sprite Replacer](https://www.nexusmods.com/scavprototype/mods/74) | Co-op | 31,240 | Last updated 20 June, so it may trail the newest co-op build | | [Player sprite replacer](https://www.nexusmods.com/scavprototype/mods/15) | Solo or co-op | 7,521 | Nine slots, numpad, skin menu, wound-view art, updated 5 November | | [ChangeSkin-Multiplayer](https://www.nexusmods.com/scavprototype/mods/118) | Co-op | 9,830 | Requires the Krokosha co-op mod; also needed by the host | | [Skin Deep](https://www.nexusmods.com/scavprototype/mods/454) | Wound screen art | 1,053 | Custom sprites for the health screen | If you play alone, start with Player sprite replacer. It does not need the core library in single-player. confirmed If you play with friends, install what the group agrees on, because skins only show up for people running a compatible mod. ## How do you install a skin? This walkthrough follows [Meow’s guide](https://www.youtube.com/watch?v=AAQoi-a-hSg&t=82s), one of the most watched on the topic. confirmed - Download the skin changer and unzip it. - In Steam, use **Browse local files**, open `BepInEx/plugins`, and drop the mod’s files in. - Launch once. A `CustomSprites` folder appears in `plugins`, with folders named 1 to 9. - Download a skin. Inside, it should have a file with “body” in the name. - Move a slot you do not need into another folder to keep it, then copy your new skin in. - Rename the skin’s folder to the slot number you want. ## How do you change skins in game? Press the numpad key that matches the slot. Slot 1 loads automatically in Player sprite replacer, and the mod remembers your last slot on the next launch. confirmed It also has a skin menu if you would rather not use the keyboard. ### No numpad? Change the keybinds. Open `BepInEx/config`, find the config file for the sprite mod, and swap each slot’s key to something else, like `Alpha1` for the 1 key on the top row. confirmed The top-row numbers control time speed in single-player by default, so pick keys you do not use for that. confirmed ## How do skins work in multiplayer? Sync rules depend on the mod, so read its page. Two cases are spelled out. confirmed - **ChangeSkin-Multiplayer:** other players see your skin only if they have the mod too, and the host has it, because the host passes skin data between clients. - **Player sprite replacer:** each player keeps their own slot and the mod shares the chosen skin. A client joining late receives skins already in the session. The host can lock skins from the menu. Versions matter here. The author of the Tailor mod noted that ChangeSkinMP 3.1.0 did not work with KrokMP 4.1.2, so a skin mod that worked last month may fail after a [co-op mod](https://casualtieswiki.wiki/mods/multiplayer/) update. confirmed ## Can you change wounds, tails and other body parts? Yes, with extra mods. confirmed - **Wound view:** Player sprite replacer reads a `WoundView` subfolder for the health-screen art, and Skin Deep also handles this view. - **Tail as a limb:** [Tailor](https://www.nexusmods.com/scavprototype/mods/671) adds the tail as a 15th injurable limb that also changes jump height, and uses the normal tail sprite, so most skins still fit. - **Species:** [Gunsaw Genetics](https://www.nexusmods.com/scavprototype/mods/324) adds 14 species, plus albino, with a chooser at the start of a run. - **In-game editing:** a community pixel editor on Nexus lets you paint body and head parts with a live preview. ## How do you make a custom Casualties Unknown skin? Start from a template rather than a blank file. Copy an existing skin folder, edit the images at the same pixel size, and keep the file names. Sprite mods look for specific names, so a renamed file will not load, and the author of Player sprite replacer warns that file layouts can change between versions of the game. confirmed Test your skin alone first. If only part of your character changes, you are usually missing a sprite in that folder, or the file is named differently from what the mod expects. ## Will skins work on the full game? Skins are the mods most exposed to art changes. The full game added two characters and a prosthesis system, so check each mod’s page for a full-release update, and keep a copy of your `CustomSprites` folder when you reinstall.
