WarBirds is a series of massively multiplayer online and offline World War II combat flight simulation video games originally developed by Interactive Creations of Grapevine and published by iEntertainment Network in 1995.

[1][2] The game includes an air combat flight simulator as well as a simulator for tanks and other ground vehicles and inspired a fan cult and conventions, and a book titled WarBirds: The Story So Far.

[1][4][5] WarBirds III was a runner-up for GameSpot's annual "Best Simulation on PC" award, which went to Flanker 2.5.

A more recent version, WarBirds 2008, includes tanks, trucks, halftracks, new aircraft, and new graphics.

[8] In 1999, some of the original development team, including John "Killer" MacQueen, Rodney "Hatch" Hodge, and Chris "Mo" Sherland, went on to form Cornered Rat Software where they developed WWII Online.
