In Total Annihilation, players will be placed within the galaxy-spanning war between The Core and ARM, who are both exhausting the resources of millions of worlds to fuel their struggle for domination. Both sides are crippled, and the forces of both sides are fighting to destroy the other once and for all. 

Total Annihilation features a campaign for each side of the conflict, with both spanning 25 missions each. The game’s The Core Contingency adds an extra 25 missions into the mix, while Battle Tactics adds 100 new missions to the game.
