A former WWII Japanese bunker in Sumarine Base, East New Britain, Papua New Guinea. Though bunkers were long cleared of any weapons and ordnance, many survivors sought refuge in the bunkers during the outbreak, hoping the steel reinforced doors and solid concrete construction would help them against the horde of Zeds.
(OOC: Got the idea of WWII bunkers and machine gun nests from
Dead Island since the Royal Palms Resort have several bunkers lining up the resort serving as maintenance sheds and war-time memory. Despite their age, they actually hold well against the Infected.)
