Quarantine zones are various sections of the city of Moresby that have been sectioned off in order to combat the spread of the Kuru infection. The main walls used to section it off were provided by the Australian Biological Institute, and are marked with the biohazard symbol.
- These regions could be considered the most dangerous places to cross on the island.
- Once the Hero crosses into it, countless numbers of infected spawn (along with other various zombies) and zero in on your position. This also applies to the refugee hospital camp set up alongside the ditch that runs through the center of Moresby.
- Unless the Hero is required to cross it as part of a quest, or is in a well-stocked, well-armed group, it is highly recommended that solo players try and avoid these particular areas.
- There is one archway that has not been barricaded by walls. So the players (and the Zombies) can enter and exit through that area.
