A free unofficial expansion pack for Command & Conquer: Red Alert 2 Yuri's Revenge, which retells, expands and continues the story of the original game. Enhanced with Ares DLL, Mental Omega strives to bring many new features to the game, including a 133-mission campaign, cooperative and a brand new faction: the Foehn Revolt.
Look, there is a reason this is called the (almost perfect, almost official) expansion pack. Its all so well done. A well crafted storyline, well-designed and expanded factions with subfactions and a campaign for Yuri (Now Epsilon) and three well designed subfactions for the Allies (America, Euro-Alliance and Pacific Front) and the Soviets (Latin Confederation, Russia and the People's Republic of China).
On top of all this, they're gonna have a second Act covering the Psychic Dominator War (rewritten of course) and an entirely new faction, the Foehn Revolt, who (as of the 8/12/15) are of mysterious origin.
Either way, a great mod with so much potential, and worthy of the title of an official expansion pack.
