Colorado Mountain Plaza is the snowbound mall near Boulder where Ellie hunts for medical supplies in Left Behind's present-day chapters. You play Back in a Flash, So Close and The Enemy of My Enemy here, fighting both infected and hostile survivors.
Ellie hides Joel and the horse in a yogurt shop and finds Weston's Pharmacy already looted. Spotting the helicopter, she fights through stalkers, restores power with a generator to open a locked gate and climbs to the wreck for supplies, then fights her way back.
Notes and recordings tell the story of Captain Regan Francis and Private Eugene Ellis. After the crash, Ellis was bitten and Francis cut off his arm to try to save him. Later Ellis killed her by mistake and died alone in an air duct.
Joel was badly wounded escaping the university. Ellie finds the supplies, stitches his wound and leaves the mall on Callus, towing Joel on a sled as winter arrives.
Weston's Pharmacy
Weston's Pharmacy is the drugstore inside Colorado Mountain Plaza that Ellie checks first in Left Behind's Back in a Flash. It has been picked clean, but it is where the chapter's search for supplies starts.
Boston
Boston, Massachusetts is the first region after the time skip and the city where Ellie grew up. You play The Quarantine Zone and The Outskirts here, and Left Behind's flashbacks with Riley take place in the same city. FEDRA holds the North End as one of the last working quarantine zones in the country.
Liberty Gardens
Liberty Gardens is an abandoned two-level mall in Boston where Ellie and Riley spend a night together in Left Behind's flashback chapters. You explore it in Mallrats and Fun and Games, and it gives the final chapter, Escape from Liberty Gardens, its name.
Silver Lake
Silver Lake is a snowbound Colorado resort town and the setting of the Lakeside Resort chapter, where Ellie is playable for most of the winter. A group led by David lives here. Its surroundings include an abandoned coal mine and the Whitefish Lake rest area.
