Total Mayhem takes Total Annihilation, bugfixes and extends it the way Cavedog might have. Early game pace is quicker, many new units added (longtime players may recognise some 3rd-party units), including a whole new 3rd tech level tier. Existing and added units have been bugfixed, rebalanced, re-modeled, re-textured and re-rendered to equal or exceed the standard of the original TA units.
Thanks to Rime's amazing new script features, it's possible to do in-place upgrades of some buildings in the upcoming version of Total Mayhem.
Great idea!
This one also auto-cloaks after it's built.
