The browser version of Doom will be compatible with Firefox and Safari and has appeared on the developer website at Mozilla. The port of the game loads in your browser window at 600×400 pixel resolution and you control the game through the regular arrow keys and fire with Ctrl. the audio was slightly delayed in our tests with Firefox 4.0.1, but 56 open tabs might be the problem.
The game can be tested at developer.mozilla.org and all you need is the latest versions of Safari or Firefox. Those who want to optimize or tailor the game can download the source code at 1.9 MB.
