D2 Survivors is a survivors-style game set in Diablo II's world. Players pick one of seven heroes and walk while their skills cast automatically as hordes close in. Each level, you choose a card to upgrade your build, then try to outlast the five acts of the campaign, followed by the Nightmare and Hell difficulties.
The game draws on Diablo II's own classes, skill trees, and items, from the first drop to a unique's gold name. It runs on your own copy of Diablo II with Lord of Destruction (patch 1.14) or Diablo II: Resurrected. The browser or desktop app reads your install once and uses its art and sound, so your saves come with you.
D2 Survivors is free, with no ads, no purchases, and nothing locked behind a paywall. Players can run it in the browser or as a desktop app, and the latest builds are available from the developer's Discord.
Your game files are read on your computer and stay there, in your browser's storage or the app's folder. Nothing is uploaded or sent anywhere. Players who want bug reports, ideas, or updates on each build's changes can join the Discord server.
