Soul Link Speedrun

Transforms multiplayer survival into a cooperative speedrun experience where all players share the same health, hunger, and saturation. Each run generates completely isolated temporary worlds that are automatically cleaned up after completion, ensuring a fresh start every time.

Work together with your team to defeat the Ender Dragon as fast as possible. If any player dies, the run ends for everyone - making teamwork and protection essential. The mod features a precise two-phase timer system that tracks your speedrun time from the moment you start until victory or defeat.

Since this mod is server-side only, players connecting to a server with this mod do not need to install it on their client. It works seamlessly with any Fabric server setup.

Give your multiplayer server a true cooperative challenge.

Shared Vitality: Health & Hunger

All players share a single, synchronized pool of Health, Hunger, and Saturation. If one player takes damage, everyone takes damage. When one player eats, everyone’s hunger bar refills.

Player A gets attacked by zombies and Player B takes damage too

Player A eats and Player B's hunger reduces too

Customize Your Challenge (New!)

Tailor the difficulty to your team using the new Settings GUI. Toggle specific mechanics to create the ultimate speedrun gauntlet:

• Shared Potions: If one player drinks a Speed potion, the whole team speeds up. But be careful—negative effects like Poison are shared too!
• Shared Jumping: Coordinate your movement! When enabled, jumps are synchronized across all players.
• Half-Heart Mode: For the absolute pros. The team's max health is capped at 0.5 hearts. One hit ends the run.
• Difficulty: Adjust the world difficulty directly within the settings menu.
• Synced Inventory: Every player in the run shares the exact same inventory. If one person picks up an item, puts on armor, or uses a potion, it happens for everyone simultaneously across their main inventory, hotbar, and equipment slots.

One Death, All Dead

If a single player makes a fatal mistake -like falling into lava- the run ends immediately for everyone.

The Objective

The run is only considered a success once the Ender Dragon is defeated.

Game mechanics & World generation

• A live timer tracks your run in the action bar and captures your final time automatically.
