You’ve killed The Butcher in Diablo before, but can you kill him in your browser?

Diablo, the seminal hack and slash action roleplaying game from Blizzard is now playable in a regular browser. Go here and you can check out the work of RivSoft, the makers of other open-source projects like a Diablo III character planner and a Path of Exile passive skill tree planner. If you don’t have your original Diablo files, you can play the old shareware version. If you own Diablo, let’s say through GOG, then you can drop the main DIABDAT.MPQ file into the browser and play the whole darned game in it. there’s probably no practical use for this, but it’s cool to stay awhile and see Tristram living in your Internet Explorer or Chrome window.
