Other titles There are a number

Operation Eagle (Codename Eagle) is a first-person shooter developed by Swedish company Refraction in 1999 and released for the PC in 2000.
Codename Eagle features a variety of vehicles, including tanks, motorbikes, aircraft, ships and even airships. The game was released with a large number of bugs and was criticised by many media for its lack of detail in the setting.
However DICE saw the game shine and soon acquired Refraction and, having learned a great deal from Operation Eagle, produced Battlefield 1942, which was ultimately a major success.
