Total Annihilation (abbr. TA) is a futuristic real-time strategy game for Microsoft Windows and Mac OS, created by Chris Taylor and Cavedog Entertainment and released on 30 September 1997 by GT Interactive. It was the first to feature 3D units and terrain, a significant achievement in the days before graphics cards with hardware-based 3D acceleration became commonplace. Two expansion packs were released, The Core Contingency on April 30, 1998 and Battle Tactics on June 30, 1998.
A remake of the game with a completely 3D graphics engine (lacking any fixated camera angle), named Spring, has been created by the Swedish Yankspankers. Total Annihilation creator Chris Taylor has also recently created the game Supreme Commander through Gas Powered Games, which bears many similarities with Total Annihilation, and has been popularly considered its "spiritual successor".
