Mechanized Assault and eXploration Reloaded is a fanmade strategy game by the community of maxr.org. M.A.X.R. is OpenSource and a remake of the old M.A.X. by Interplay from 1996 featuring network games based on TCP/IP (e.g. over the internet). The game can be played in a turn-based mode (with or without time limit), or simultaneous mode (all the players take their turns at the same time), and features combat in air, land, and sea. Three resources are present on the maps - raw materials, that are needed to manufacture units, structures and ammunition, fuel, that power generators need to function, and gold, that is used to purchase upgrades. This game is a mix of realtime and turnbased strategy with battle chess character. It is released under the GPLv2 and GFDL
If you own the original game CD the additional tool "resinstaller" can extract and copy the original graphic and sound files to their proper places in the M.A.X.R.'s folder structure.
The creation of a free graphics set started in 2008 and M.A.X.R. can be played as standalone too.
