VoxelStorm Ltd was an independent game studio running from 2012 to 2018, noted for building all its game engines from scratch.
VoxelStorm has been re-born as Armchair Software, and the classic games are still available - see voxelstorm.com.
The plan is to gradually release all VoxelStorm code as open source, so long-term fans and the entire gamedev community can benefit. Repositories containing open source VoxelStorm code are grouped here - explore!
