Overpass is a map featured in the Fire Sale DLC.
With a nationwide no-fly zone being enforced by the North Korean Air Force, the US military sets its sights on regaining control of overland supply routes. The KPA isn't prepared to give any ground -- even this stretch of derelict highway.
Overpass is a stretch of highway covered in cars. There are two holes in the highway, so it is advisable to watch one's step while on the highway. At one end of the road, there is an overwatch position over the entire highway. The broken MRAP vehicles and Humvees provide excellent cover for skirmishes.
