Where can I play?

Undermine Squad runs in the browser, with no download, account or app store. Open undermine-squad.com/spielen and play. If you like, install it as an app: it then has its own icon, starts full screen and also works without internet.

On a computer in the browser

On a PC, Mac, Linux or a Chromebook you play in an up-to-date browser:

Browser	Play	Install as an app
Google Chrome	yes	yes, with the install icon in the address bar
Microsoft Edge	yes	yes, the same way
Mozilla Firefox	yes	no install button; you play in the browser as usual
Safari (Mac)	yes	yes, from Safari 17 via File → Add to Dock

You control the game with keyboard and mouse: WASD or arrow keys, E digs, Q throws, a right click opens the context menu. Every key is listed under Controls.

On a computer: digger, money and goal at the top, the action bar at the bottom.

On phones and tablets

On Android, iPhone and iPad you play in the browser with touch. The game detects the device and shows the right controls: a stick on the left and big buttons on the right on phones, an action bar on tablets. Hold the device in landscape for the best view. More under Phone and tablet.

On a phone: Dig, Jump and Throw on the right, your thumb steers the stick on the left.

Note

On phones the game switches to full screen on your first tap in a round, where the browser allows it. Installed as an app, the browser bar is gone completely.

With a gamepad

A controller via USB or Bluetooth works on computers, tablets and phones, for example an Xbox or PlayStation controller. Connect it and press a button, the game will report it. Layout: stick or d-pad walks, A jumps, X digs, B throws, Y is the double action, LB and RB switch the digger, Start pauses. The full table is under Phone and tablet.

Install as an app

Undermine Squad is a web app (PWA). Installed, it gets its own icon on the Home Screen, in the Dock, the taskbar or the Start menu, starts without the browser bar and, once loaded, also works offline.

On computers and Android, app and browser share saved games and crew. On iPhone and iPad the app has its own storage; take your crew along with Main menu → Crew → crew file.

The main menu shows Install as app at the top right when your browser supports it. On iPhone, iPad and Mac the button explains how. If the game is already installed, the button is gone.

At the top right of the main menu: “Install as app”.

Chrome and Edge on a computer

This works on Windows, macOS, Linux and ChromeOS:

1. Open undermine-squad.com/spielen in Chrome or Edge.

2. Click Install as app in the main menu, or the install icon on the right of the address bar (a screen with a downward arrow).

3. Confirm with Install. Undermine Squad opens in its own window and from then on sits in the Start menu, the Dock or the launcher.

Diagrams, not screenshots

The pictures of the install steps are simplified drawings. Depending on the browser and system version, menus and icons look a little different and may sit elsewhere.

Playing offline

Once loaded, the game stores its files on your device, as an app and in the browser. After that it also starts without internet, for example on a train or a plane. Saved games and crew are stored on the device too. Music loads the first time you hear it; what you have already heard plays offline as well.

New versions

When there is a new version, the game shows New version available at the bottom with a Reload button. Your current round is saved first. What is new is in the changelog.

Removing the app

Like any other app: on a phone long-press the icon and choose Remove; on a computer use the menu ⋮ in the app window and Uninstall (Chrome, Edge), or drag the icon out of the Dock and delete it from the Applications folder in your home folder (Safari). Saved games in the browser are not affected.
