Mortal Shell II · Voice Co-Pilot & Boss Guide
70% of Mortal Shell II players never saw the ending.
Mortal Shell II is one of the most underrated soulslikes out there, and one of the hardest to finish. Overlord runs beside it on your PC, watches your screen, and tells you which area you are in, where the next Tarstone, Ova or weapon is, and how to beat the boss in front of you, out loud through your headset.

The numbers behind the quit
It is not that the game is bad. It is that most people never see the end of it.
These are public figures, not marketing. They describe a very large group of players who paid full price and stopped before the credits rolled.

We cannot promise you will finish it. We can put a guide that knows the fights beside you while you try.
No completion, score or outcome is guaranteed. Overlord gives guidance, not results.
“Many players will find themselves quitting early on and ultimately feeling cheated for their purchase.” — player discussion, r/ShouldIbuythisgame
What Overlord is
A guide that talks you through, not a tool that plays for you.
Overlord runs on your computer, beside the game. It is built for single-player play and it is deliberately simple about what it touches and what it does not.
Reads the screen
With your permission, it watches your screen: the view a person sitting beside you would have. It doesn't read or change game memory, it doesn't inject code into the game, and it never presses a key for you.
Speaks in real time
It calls the next objective, the item you just walked past, and the fight that is about to turn — out loud, while you play, instead of on a second monitor.
Knows Mortal Shell II's map
Preloaded with 30 areas, 100 items and 31 bosses, from Magdalena, Lady of the Woods to Vellen, Lord of Mammon, so it can point you to the loot and the fight, not give generic advice.
Three in-character voices
A celestial goddess, a field commander and a shadow guru, each with its own voice from Google Cloud Text-to-Speech.
On your machine
Runs on Windows 10/11 or Linux beside the game you already own, with every feature on both. Answers and the voice come from our cloud service, so it needs an internet connection.
Built for single-player
Overlord is made for single-player games. It isn't meant to give anyone an edge in competitive online play, and we don't make guides for competitive multiplayer games.
01
Start it beside the game
Launch Overlord on your PC, then launch Mortal Shell II on Steam.

It watches the screen
Nothing is installed into the game. You choose which screen it can see, the first time it asks.
03
It talks you through
Voice callouts for the objective, the loot and the boss in front of you. Ask it a question any time.

Does Overlord change or control the game?
No. Overlord watches your screen, with your permission, the way a person sitting next to you would. It doesn't read or change game memory, change game files, inject code or press keys for you. Each game sets its own rules about outside help, so check the terms of the games you play.
What do I need to run it?
A Windows 10/11 or Linux (Ubuntu/Debian) PC beside the game you already own. Every feature works on both. There is nothing to install into the game itself and no patch to manage. You also need an Overlord AI account and an internet connection for answers and the voice.
How much does it cost?
The demo is free: 30 minutes of live play with no credit card, one trial per person. After that, Subscription is $14.99 a month or $149.99 a year for one machine, and Pro is $39.99 a month or $399.99 a year for three PCs. You can cancel any time.
Does it support Mortal Shell II?
Mortal Shell II is researched and preloaded. Overlord knows its areas, items and bosses, follows you from area to area, and talks you to the item you ask for. It's built for single-player play.
Get past the boss that made you quit.
Thirty minutes free, no card. See whether a co-pilot that has read every fight is the thing that finally gets you through.
