These TA papercrafts is from TA paper models. Total Annihilation (TA) is a real-time strategy video game created by Cavedog Entertainment, a sub-division of Humongous Entertainment, and released on September 30, 1997 by GT Interactive for Microsoft Windows and Mac OS. It was the first RTS game to feature 3D units and terrain. Two expansion packs were released, The Core Contingency on April 30, 1998 and Battle Tactics on June 30, 1998. After the closure of the Cavedog Entertainment Studios in 1999, the intellectual property fell to Infogrames. In March 2010, Total Annihilation was re-released as digital download from Stardock.
Total Annihilation is no longer supported, due to the closure of Cavedog. With Gas Powered Games, lead designer Chris Taylor went on to create Supreme Commander, popularly considered the "spiritual successor" of Total Annihilation. A remake of Total Annihilation named XTA, lacking any fixed camera angle, has been independently produced. It uses the open source completely 3D graphics engine named Spring. Also, the Total Annihilation 3D (TA3D) project was begun in the summer of 2006. Total Annihilation is currently played online via The WarZone, Game Ranger, and Phoenix Worx gaming lobbies, with The WarZone being the most active.
