DELTASTACK

MULTI-MOD MANAGER

Most mods only work one at a time. DeltaStack patches every mod you pick, merges them together, and launches one game with all of them in it.

♥ PREVIEW

A first look at the app. It's dressed for the Dark World.

Stack mods

Turn on as many mods as you want per chapter. They get merged piece by piece: code, sprites, rooms, sounds and text.

Check first

One click shows which mods touch the same things, which one wins, and whether the code edits will merge cleanly.

Fixes itself

If two mods can't be combined, it tries a different order. If that fails, it leaves out as few as it can and tells you which ones.

Verified merges

After merging, it checks that every mod's changes made it in and that the game can load the result, before you ever launch it.

Saves protected

Your saves get backed up before every apply, and one button puts the original game back.

Browse & install

Search mods from inside the app, read what they do, and install with one click.

♥ HOW IT WORKS

Three steps. Your game stays safe the whole time.

Pick your mods

Install from the built-in browser, paste a link, or drop in files. Tick the ones you want.

Check them

See what clashes before anything changes. When two mods edit the same thing, the lower one in the list wins.

Apply & Play

Your saves get backed up, each chapter is built with your mods merged in, and the game starts.

Is there a free trial?

Yes. Every copy starts with a 1-hour free trial. After that, applying, installing and updating mods need a license key. Restoring the original game, browsing mods and your save backups keep working without one.

What does a lifetime key get me?

Full use for good, and DeltaStack keeps itself up to date: new versions download in the background and you click "Restart to update." Every update is signature-checked before it installs.

Does it mess with my game files?

Before it touches any game file, it keeps an untouched copy of it. It also won't change anything while the game is running, and it checks you have enough disk space first.

How do I go back to the normal game?

Press "Restore vanilla." Every file goes back exactly as it was. If the game updates, DeltaStack notices and takes a fresh clean copy instead of restoring an old one.

What does it run on?

Windows 10/11, Linux, and Apple Silicon Macs. It finds Steam installs on its own, or you point it at your game folder.

♥ WHILE YOU WAIT

The Vessel stirs. Dodge everything it throws and see how long you last.

  1. Every week the board resets.
  2. Whoever survives The Vessel the longest that week wins.
  3. Prize: a free lifetime DeltaStack key when it launches.
NOT LIVE YET. The board opens once scores are checked on the server, so nobody can fake a time. For now, your best time only lives in this browser. Practice up.
