Hell Let Loose: Vietnam Wiki - Maps
Thanh Hóa Bridge
The only one of the 6 confirmed launch maps named ahead of release -- inspired by a real Vietnam War location and operation, like all of the game's maps.
5 Additional Unnamed Launch Maps
Five further large-scale maps are confirmed for launch alongside Thanh Hóa Bridge, spanning jungle, rice paddies, beaches, hills, and river terrain -- specific names have not been published as of this writing. Additional maps are planned post-launch via updates.
