It should be noted that both types of Tesla tanks are represented in Retaliation: the prototype based on the Radar jammer from Counterstrike and the final Tesla tank from The Aftermath.
Specific units such as Volkov, the Soviet Super tank and Allied stolen nuclear armed MiG also appear in certain missions. Special units added in The Aftermath such as the Tesla tank, Field mechanic, MAD tank, and Chrono tank are available in later missions.
Instead of the main force deciding the outcome of the war, the player is assigned to a certain auxiliary command - in the Allies' case, an American detachment led by general Carville, while Soviet commander is under the command of general Topolov, both of which have been entrusted with several 'secret projects'. The campaigns in Retaliation are similar for Allies and Soviets.
