AI War 2: The Neinzul Abyss

AI War 2 is a big strategy / RTS hybrid that upends many of these two types of conventions. Occupy territory unnoticed, carefully build your empire, and adapt to the growing Galactic Battlefield. It is also a sequel to [Arcen's] enormo-space RTS AI War, which we called "one of the best strategy games of the year" in 2009 (Tom Sykes,PC Gamer)
"Smart Warfare 2" is a grand strategy / RTS hybrid, and players will face alien overlords who conquer the Milky way.
but your enemy has made a fatal mistake, which is to underestimate your abilities. Players will steal enemy technology, compete for enough territory, strengthen the base and launch a counterattack, but each player's behavior will cause feedback from artificial intelligence, so choose the target carefully.
