Ignition City is a five-issue science fiction comic book limited series, written by Warren Ellis and illustrated by Gianluca Pagliarani.

After some brief initial work in 2006, the series was not mentioned again until after the release of his Aetheric Mechanics in 2008.

[1] Inspirations included the Flash Gordon and Buck Rogers serials, the show Deadwood, the artist Magdalene Veen,[2] the film Metropolis, the Berlin Tegel Airport, Ray Bradbury's short story "Rocket Summer", Alan Moore's comic The League of Extraordinary Gentlemen, and his own Ministry of Space comic (which was in turn inspired by Dan Dare).

[3][4] Ignition City is set in an atompunk/dieselpunk alternate history in the year 1956; in this timeline, World War II was interrupted by a Martian invasion.

Ignition City itself is Earth's last spaceport; a circular artificial island located in equatorial waters.
