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.
Absolutely love the mod, the campaign is challenging, and the skirmish is entertaining.
Only problem I have is the lack of being able to save games, though I understand this is caused by the ARES plugin.
