Command & Conquer: Red Alert: Counterstrike is the first of two add-ons for Command & Conquer: Red Alert, launched in 1997 and introducing new missions for both the Allies and the Soviets. It marked the first expansion to add new units, though these were limited to the campaign. The standout feature of this expansion was the inclusion of four hidden Ant missions, featuring a brand-new "faction" of adversaries known as the Giant Ants. Adds 16 new single-player missions and a variety of new multiplayer maps crafted by the original creators of Command & Conquer: Red Alert.
