Command & Conquer Red Alert 2(MOD Unlocked) is a 2.5D real-time strategy computer game developed by Westwood Pacific and released in October 2000 as the follow-up to Command & Conquer: Red Alert. Although not originally envisioned by Westwood Studios, Red Alert 2 was created following the success of the original Red Alert. Set in the early 1970s, Red Alert 2 picks up at the conclusion of the Allied campaign of the first game, making the original idea of Red Alert being a prequel to Tiberian Dawn difficult to realize and separating the Red Alert universe as its own series. In October 2001, the expansion pack Yuri's Revenge was released.
