Platform

Primary: our account is set as the home Xbox of your console ("My home Xbox"), so the game is shared with your own profile and works offline — that is one slot on one console. Secondary: you sign in to our account and launch the game from it, and the console has to stay online. The activation code is an extra option: it is redeemed on your own account, and the game stays there forever.

You install the game from our account and set our account as the home one ("My home Xbox"): after that you play from your own profile, and the progress and achievements stay yours. It works offline.

You sign in to our account and play right from it. A permanent internet connection is required and only the issued profile can be used. It costs less than the primary access.

Activation code

A bonus way to buy: you get a 25-character code and redeem it on your own account. The game stays with you forever, no other profiles and no sign-in to a shared account.

About the game

All aboard the submarine! Shelldiver is an incremental game about a turtle fishing jellyfish and selling them at their little shop. Help our senior protagonist upgrade their equipment, explore various biomes and oceanic depths, and help out their local turtle population – maybe right after a well-deserved nap!

Your primary resource is jellyfish – the favorite meal of these turtles! With your handy bubble gun, you can chase and capture various unique types of jellyfish, each with their own unique spin – and taste, probably – then sell them at your little shop. Electric jellyfishes, mutant amalgamations, hellish jellies who explode when nearby – the more you collect, and the faster you do, the more money you get to invest back into your business!

On top of the gelatinous creatures, you will also have other types of resources floating about near the ocean floor to scrap for parts! Use your powerful laser blaster to take apart human trash, crystal rocks, mushrooms, and other distinct components, then use them to upgrade your submarine, tools and more.

The more you collect, progress and explore, the more opportunities you'll get to improve your skills. With a large branching skill tree, you can pick and choose your favorite perks and customize your future expeditions to maximize the things you want most – from your oxygen tank to the size of your shop!

The ocean is vast, and your clientele is demanding! Unlock and explore various unique biomes – from volcanic waters to crystalline caverns – as well as their varying depths and unique resources. Just don't forget to check your oxygen supply!

How to activate

Guide for Xbox One

Primary — the game is shared with your own profile

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Now open "Settings" → "General" → "Personalization" → "My home Xbox" and choose "Make this my home Xbox". This is what shares our games with every profile on your console.
3Switch back to your own profile, open "My games & apps" → "Library" and install the game. The internet is only needed for the download.
4Launch the game from your own profile: achievements, saves and progress stay yours, and after the installation the game works offline.

Only one console at a time can be the home Xbox for our account — that is the slot you bought. Please do not change the password, the email or the two-factor settings of the account, or the access will be blocked.

Secondary — you play from our account

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Open "My games & apps" → "Library", switch to our profile in the top-left corner and install the game.
3Launch the game while our profile stays signed in, and keep the console online: the licence is checked over the internet.
4Use your own profile for everything else — the game stays available as long as our account is signed in on this console.

Secondary costs less, but it needs a permanent internet connection and our account stays signed in on your console.

Activation code

1On the console open "Store" and go to the "Redeem code" section.
2Enter the 25-character code from your order and confirm the activation on your own account.
3After the activation the code is shown as "Used" — but you can reinstall the game from your library at any time.

Notes for Xbox One

Important

Do not change the password or the email of our account, do not disable two-factor authentication and do not activate Primary on several consoles at once — that blocks the access. Details are in the "Warranty" section.

How to play online

Online modes work if you have an active Xbox Game Pass Core or Ultimate subscription on your own profile. Our account does not replace a subscription.
