"" was released on October 23, 2000. It featured a Soviet invasion of North America with tanks, conscripts, large airships, and psychically dominated anti-ship giant squid. Since that game lacked reference to the "Tiberian" series, the connection established in the first "Red Alert" game became unclear. However, it has been implied by the original creators of the series, now working at Petroglyph Games, that "Red Alert 2" takes place in a parallel universe that came about as a result of time travel experiments taking place some time into the "Tiberian" series. "Red Alert 2" was received fairly positively with an aggregate score of 86% from GameRankings.
