Command & Conquer: Red Alert 2 - Mental Omega

Mental Omega is a free unofficial expansion pack for Command & Conquer Red Alert 2 Yuri's Revenge. It started off as a balance modification and after a few years, it had grown into an unofficial sequel with new campaigns for the Allies, Soviets and Yuri. Now, version 3.3 marks the end of the long road and is the final iteration of the Mental Omega mod series.

1982. Hungering for revenge, the Soviets launch a full-scale invasion against the United States of America. The Allied primary defense network is shut down under mysterious circumstances and the only thing between the Soviets and America is a tiny little ocean. The third Great World War begins, where the strings are pulled by a single man - a remnant of Stalin's psychic legacy.
