Set during the torrid backdrop of the Third Gulf War in 2010, the continuing war on terror has escalated into a new form of horror.
In an effort to strengthen their attacks against the monolithic American war machine, the insurgents have forcibly secured the assistance of a major pharmaceutical company operating in that area and have developed a new kind of terrorism. Bio-terror.
The drug induced mutation process was quite a success for the insurgents, with their soldiers gaining the ability to heal rapidly against bullet fire, and literally immune to all forms of chemical weapons.
In Left Behind, you play as an elite group of soldiers, crash-landing in an evacuating Blackhawk right in the heart of the very region where the mutated insurgents are let loose. Stranded, with no communications equipment, and only the ammunition carried on your backs, you need to shoot, slay and slaughter your way ahead to a viable SNR location. There will be no backup, no help, and no hope, for you have been Left Behind.
