You can check progress on WebGL client here: http://manicdigger.sourceforge.net/webgl/game.html

I’m trying to make a web browser version of the game using JavaScript, WebGL and Script#. New client will not require any plugins (like Flash, Java, Silverlight or Unity). It will still be possible to use desktop C# client and play together on same servers.

See HexGL and Trigger Rally Version 2 games to check if you will be able to run MD in web browser.
WebGL works best on Windows Vista, 7 and 8, using Google Chrome or Firefox. To run on Windows XP you have to unlock WebGL. WebGL also works on Linux, Mac and even Android.

2012-10-22 nightly version added grenades.

I’m making a mod that transforms the game into a first-person shooter.
