Denver is one of the only cities which boasts a high percentage - though still under 50% - of people not infected by The Flare. It is located in Colorado and appears in The Death Cure. It has an extremely high level of strict security, with bounty hunters often patrolling the areas looking for Immunes which they then sell them to WICKED. The city eventually caved in to the Flare after hundreds of Cranks invaded and took control of the city.
