1942: First Strike is the last title in the 1940 series so far, released in 2009 for iOS operating devices. Despite using a very similar logo and HUD, it is a different game from 1942: Joint Strike.
Due to being on a mobile device, this game uses touch controls. All systems from Joint Strike have been carried over to this title, with the addition of a stats upgrade system, returning from the NES version of 1943: The Battle of Midway.
The game consists of two chapters. The first chapter, which has eight stages total, is inspired by the early titles in the series, where you fight the Japanese on the Pacific. The second chapter, which has five stages, is more or less a port of the stages from Joint Strike.
