Mental Omega: Almost Perfect Yuri's Revenge is a free unofficial expansion pack for Command & Conquer Red Alert 2 Yuri's Revenge (from Westwood Studios). The mod retells and continues the storyline of the original game. Enhanced with Ares DLL, Mental Omega 3.0 strives to bring new features to Red Alert 2 Yuri’s Revenge.
While Mental Omega 3.0 itself is almost ready for the first public release, it cannot happen until AttachEffect feature is implemented into Ares post v0.3 which hasn't arrived yet. If you're a modder, you can grab latest unstable version and run some tests with it at Ares.strategy-x.com
