About this mod Machine translation

The FriendlyFire mod allows you to hold down a trigger key to redirect cards so they can attack allies or apply block and power effects to teammates or enemies.

FriendlyFire

🎮 Module function

This mod adds an interesting tactical dimension to Slay the Spire 2's combat system!

  • **Redirect card effects**: During combat, hold down the trigger key (default is the **ALT** key) to drag the card to an ally or enemy, applying its effects to the target accordingly.
  • **Tactical Prank**: You can secretly add **Block** or **Strength** effects to your enemies, or "punch" your teammates when they least expect it!
  • **Visual Cue**: When you hold down the trigger key, a red box will appear at the top of the screen to indicate that the feature is activated.

⚙️ How it works

The core of the module is to change the target logic of the card. Typically, cards can only target a specific target (enemy or self). After enabling this function, you can break through this limitation and freely choose the objects on which the card will be effective, thereby creating many unexpected tactical combinations and interesting gameplay.

📥 Installation Guide

  • Extract the downloaded ZIP file into the game's `mods/` folder (for example: `Steam\steamapps\common\Slay the Spire 2\mods\`).
  • After unzipping, there should be a directory named **`FrendlyFrie`** in your mods folder.
  • Launch the game and click "Yes" when asked whether to load the mod.
  • You can change hotkeys or other settings by modifying the `friendly_fire_config.cfg` file.
**⚠️ IMPORTANT**: In multiplayer games, **all players must use the same profile**. Different settings may cause game data to be out of sync and cause disconnections.

✨ Usage suggestions

  • Try using "Defense" cards to add armor to your enemies, or use "Strength" cards to strengthen your teammates and see what sparks will come out of the collision.
  • In co-op mode, make some harmless jokes with your friends to fill your tower climb with more laughter.
  • Pay attention to reasonable use to avoid "accidentally injuring" teammates at critical moments and causing the team to be wiped out!

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
