Saving, offline play and known limits in Operation Epic Fury

Your campaign is saved

While a campaign runs, the game saves it to your browser once every game day. Next time you open the game, the briefing shows Continue campaign with the day and the oil price, such as "day 37, oil $88".

• There's one save. Pressing New campaign (or Start a new campaign) replaces it.
• It lives in this browser on this device. It doesn't follow you to another browser or device, and there's no account to sign in to.
• Clearing the site's data deletes it. So does a browser that blocks site storage or has none free: the campaign then can't survive a reload.
• A finished campaign clears the save. That includes a recall or a recession. If you lose and want to carry on, press Fight on on the result screen before you close or reload the tab. See How to play.
• An older save may not load after an update. If we change how the simulation works, saves from before the change are dropped instead of being misread.

The Daily Crisis isn't autosaved. Reloading ends a Daily run, and a Daily run never touches your campaign save.

You can still pause with Space and leave the tab open. A full campaign takes about 48 minutes at 1×.

What needs a connection

Parts of the game need the internet:

• The map's relief and sea-floor shading come from the open AWS Terrain Tiles dataset.
• Radio clips are fetched from the game's server when they're spoken.
• The Daily Crisis leaderboard, and the game's catalogue and anonymous statistics, talk to the game's server.

The simulation itself runs on your device.

What's stored on your device

The game keeps these in your browser's local storage, not in cookies:

• your saved campaign
• a random statistics id that isn't linked to your name or email
• your settings: sound, music, radio chatter, how many raids to offer as battles, and which Desk drawers are open
• whether you've seen the watch officer's checklist
• the name you last used on the Daily Crisis leaderboard, and which dates this device has started a Daily run on
• the signed licence for anything you've unlocked, if purchases ever open

Clearing the site's data removes all of it.

Radio voices

The radio net uses about 570 pre-recorded neural-voice clips played through a radio filter with static and beeps. It doesn't use your device's speech engine, so no text is sent to your browser or operating system provider to be spoken. The radio icon in the top bar cycles the chatter between full, key events only, and off. The music and sound icons beside it switch those on or off.

What it isn't

• It's a strategy game, not a simulator. The oil market is a simplified model tuned to behave plausibly. It isn't a forecast or a source of real-world information about oil markets.
• Combat is statistical unless you take command of an escort battle. Then it's real-time, but it still uses the game's odds.
• It's fictional. The conflict that inspired it was still going on when the game was made, so every faction, nation, person and ship name is invented. The equipment and figures are real.

Devices

It runs in the browser on desktop, tablet and phone, with no install. There's no iPhone or Android app yet.
