Configurable scaling of enemy health, block value, and abilities (by number of players) in single and multiplayer games to increase the challenge of the game.

BetterMultiplayerScaling

🛠️ Configurable options

The mod contains **8** configurable options, allowing you to tweak the game however you want:

  • **Fixed Health Bonus**: Adds a fixed amount of health to all enemies, not affected by scaling factor or player count. Great for increasing the difficulty of early levels without overly affecting later levels.
  • **Additional scaling percentage per player**: Additional scaling percentage for each additional player in the lobby. The default value is **5%**. This number is multiplied by the number of players in the lobby and added to the **base scaling percentage**.
  • **Base scaling percentage**: The default scaling ratio of the lobby. The default value is **100%**. Setting it below **100%** can effectively **reduce** the monster's health.
  • **Minimum number of players required to take effect**: How many players need to be in the lobby for this mod to **take effect**. The default value is **2**. Set to **1** to make it work in single player as well.
  • **Elite Health Multiplier**: The percentage by which the health of elite enemies should be multiplied. The default value (i.e. the original value) is **100%**.
  • **Boss Health Multiplier**: The percentage by which the boss enemy's health should be multiplied. The default value (i.e. the original value) is **100%**.
  • **Ability Stacking Multiplier**: The ratio by which the values ​​of "Artifact", "Plating", "Buffer", "Slippery" and "Easy to Startle" are applied to an enemy. The default value (i.e. the original value) is **100%**.
  • **Block value multiplier**: The ratio by which the enemy's value should be scaled when it obtains the "block" effect. Does not affect the Plating or Susceptibility values ​​applied to enemies. The default value (i.e. the original value) is **100%**.

🧮 Calculation principle

**The calculation formula is as follows:**

`Standard game calculation * (base scaling percentage + (number of players * additional scaling percentage per player))`

**Give me a chestnut 🌰:**

Using default values ​​(base 100%, 5% per player) in 8-player co-op:

`800% * (100% + (8 * 5%))`

= `800% * (100% + 40%)`

= `800% * 140%`

= **1120%** total scaling (original is 800%).

This means that if an enemy has 14 health in solo mode and 112 health in vanilla 8-player co-op, with this mod it will have **156 health** in 8-player co-op. If **Health Points Fixed Bonus** is also configured, an additional bonus will be added on top of this.

🎯 Usage suggestions

  • **Challenge yourself**: Increase the `additional scaling percentage per player` and `base scaling percentage`, so that even high-player teams will feel a lot of pressure!
  • **Balanced experience**: If you feel that the enemies in the late stage of the original multiplayer mode are too "brittle", you can approp …

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.
