Own War

 
Vehicular combat building game
In Own War you create vehicles from basic blocks and drive them into battle against other players.

The game is libre software: the AGPLv3 license permits you to do whatever you want with the source code provided you grant the same permissions to other people.
Características:
•	You can create any vehicle using basic blocks. There are quite a few blocks to give your creations detail as well as functional blocks such as wheels, weapons,…

•	The damage system is voxel-based: vehicles are torn down block-by-block.

•	The game supports multiplayer. You can join any server and host your own too.

•	Since the game is entirely free (as in freedom) you can modify it to any extent. In fact, I highly encourage people to tinker with it and experiment with what works & doesn’t work.
