Für Jagged Alliance: Back in Action (ab 4,25€ bei kaufen) steht mit "Shades of Red" eine Download-Erweiterung für 3,99 Euro bei Steam zum Kauf bereit. "Shades of Red" ist eine neue Mission mit vorgegebener Söldneranzahl, die auf dem Jagged Alliance-Roman 'Shades of Red' von I.M. Wong basiert. Die DLC-Erweiterung ist sowohl mit als auch ohne Taktikmodus spielbar, soll "über eine Stunde lang" sein und dabei die Hintergrundgeschichte von drei Charakteren vertiefen.

"The threat of a nuclear disaster has never been greater! The nefarious terrorist Ante Silevic has captured an atomic weapon and plans to attack a meeting of the world leaders in Eastern Europe. Three hardened mercenaries are our only hope to save the world from total chaos. Ivan Dolvic, Kyle 'Shadow' Simmons and Cynthia 'Fox' Guzzman must infiltrate the enemy base deep in the woods and put a stop to his activities. But in an unfortunate turn of events, Fox is captured by Silevic's henchmen before the mission even starts. Can you manage to free Fox, complete the mission and save the world?"
