Hi everyone,

MegaMek: new stable release 0.34.1

MegaMek is a networked Java clone of BattleTech, a turn-based sci-fi boardgame for 2+ players. Fight using giant robots, tanks, and/or infantry on a hex-based map.

Just 2 days ago, we finally created the latest MM stable release, which now features complete TW ground combat rules (with some very minor exceptions, some support veehicle stuff, like airships, is not implemented, and building-basements are missing).
After more than 2 years since the last stable release, I hope you all enjoy the progress we've made.
Please find it for download here: read more

New Stable Release! Final BMR release.

Our friendly neighborhood administrator, Beerockxs, just release stable 0.32.0. As the release candidate has been available for a week with zero bug reports, it has been decided to be "good enough".

This will be the final release for the BMR. Going forward, development will be done on the Total Warfare rules set, and BMR rules (where different) will be converted over.

As a rule, those sections of the rules that do not currently have a new version (Artillery, for example) will be left in place until the suitable replacement rules have been published.... read more

MegaMek v0.30.0 released

After more than two years of development, the next stable
version of MegaMek has been released!!!

This release is accompanied with some changes to the package
structure, and with a new way of handling version numbers.
Now, all development snapshots will go to the "development"
package. Stable releases will be in the "stable" package. Any
release files that let you upgrade an existing installation will
be in the "upgrades" package. Media files (which should be
portable between all versions) will be in the "media" package.
The "utilities" package remains the same. Also, the current
stable branch has a new version number, v0.30.0, instead
of re-using the old development numbers of v0.29.x; the first
release of the new development branch will be called v0.31.0.... read more

Announcing the Bug Hunter of the Month!

Because it has been nearly a year since our last stable release, and our bug list is still huge, I've decided to start recognizing the MegaMek Bug Hunter of the Month. While this honor has no practical value (much like MegaMek:), it does grant bragging rights. Hopefully, this will be sufficient motivation for the developers to start killing bugs in earnest.

This award is granted based on the number of tracked bugs that have been recorded as "fixed" in history.txt. If you've made a change and failed to update history.txt, or if your change wasn't for an item in the Bug Tracker, it does not count. While it is perfectly acceptable to add a report to the Bug Tracker and then fix it, you are not allowed to get credit for bugs fixed in previous months. Feel free to update the current history.txt for unclaimed bugs that you've squashed in June.... read more

MegaMek is June POTM

The good folks at and Linux Magazine have declared MegaMek the June, 2003 Project of the Month! To celebrate, the project's developers are scrambling to kill all bugs (priority 4 and greater) and release the next stable version: v0.29. We ask all players to download the latest developement snapshot (currently v0.29.21) and help us find any bugs hiding in the code and confirm that the recent fixes have fixed the old bugs (see history.txt or the release notes to see what bugs have been fixed).

MegaMek v0.23.0 available

MegaMek v0.23.0 has been released. This is a quick release including support for pushing, and most forms of unit displacement. Also, a readme file is included, so if you were having trouble, now there's a place to get some answers.
Development versions from CVS for the next few days may be slightly unplayable, as I have some ideas for major revisions of the board display code and they may take a little while to get working.
