Your first Outbreak session

Check the requirements first

The host’s unsupported-browser message recommends a current Chrome or Edge. Its startup checks include JSPI, WebAssembly exception handling, tail calls, SIMD and isolation headers supplied by the host itself.

WebGPU has a separate role: it accelerates graphics. The host can try a slower software renderer when no adapter is available. A graphics pass alone does not prove that every startup requirement is met.

Start in this order

1. Pick File #1 or File #2 below. If you are joining friends, match their edition.
2. Wait for the external page to finish its initial loading. It fetches resources automatically; the first start may take a while.
3. Choose a player name if prompted. Use the page’s Play control when it becomes available.
4. Click the game view so it receives your keys. Press Enter for Start, and J to confirm.
5. Choose your game mode inside the game. Use the edition-specific online guide when joining a friend.

Both buttons open outbreakweb.com in a new tab.

Before the first scenario

Default WASD movement is relative to your character. A and D turn; they do not strafe. F1 shows the host’s controls. Use its Settings panel if you need to remap a key.

On touch devices, the host supplies on-screen controls and recommends landscape orientation. The same browser startup checks still apply.

Finish with a backup

Save inside the game, then export the matching File’s memory card from the host’s Saves panel. Closing a tab, changing a player name or selecting a different browser does not create a backup.
