New Horizons is a mod made in tribute to the classic real time strategy game Command & Conquer: Red Alert 2: Yuri's Revenge, originally made by Westwood Studios. New Horizons vastly expands the original game with an emphasis on realism, while at the same time preserving the elements that made Red Alert 2 unique. Youtube: 'RA2YR: New Horizons Mod'
