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.
Core Rattlesnake L3 Super-heavy assault tank in undeployed state with 15 lasers. Not 14. Not 2. Fifteen. Model and concept by gamma.
Core for the win with giant laser death machines!
...15, eh?
