Shared health, hunger, saturation. Synced jumps, synced effects, half-hearted mode. The most chaotic shared health mod!



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

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

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

A live timer tracks your run in the action bar and captures your final time automatically.
Late-joining players can hop in mid-run and instantly sync to the current state, or join fresh after a reset.
When a run ends (via death or victory), simply click the text in chat to immediately generate a fresh world and start a new run.

/start - Begin a new speedrun attempt (generates fresh worlds)/reset - Instantly restart the current run (No OP required)/stoprun - Admin command to stop current run (requires operator)/runinfo - Display current run state, timer, and shared stats/settings - Open the settings menu/chaos - Open the game mode selector menu

Welcome to the Soul Link Speedrun FAQ! Here you will find answers to the most common questions regarding gameplay mechanics, hosting, and technical support.
Please read this carefully before asking for support.
Aternos has an automated popularity threshold for mods to appear in their public search. Until we reach that threshold, please consider using Essential.gg or e4mc to host your sessions easily without a dedicated server.
No. The mod relies on modern libraries (specifically Fantasy for runtime world generation) that are exclusive to the Fabric loader on newer versions. Porting to Forge or older versions is not technically feasible.
No. The mod is fundamentally designed as a Speedrun challenge. The core mechanic dictates that death results in a "Game Over" to encourage replayability. If you prefer a persistent survival experience with shared health but without resets, we recommend looking for "Shared Vitality" alternatives.
Currently, worlds are generated as temporary instances via the Fantasy library. When the server closes or the run ends, the world is deleted.
The mod is designed to generate its own temporary worlds. Using it on an existing standard vanilla save is not recommended as it may conflict with the mod's loop/reset mechanics. Always backup your data before testing!
You can toggle special game modes and difficulty settings in-game. Simply run the command /chaos to access the configuration menu for Shared Jumping, Half-Heart Mode, and other modifiers. Your changes will be applied in the next run.
