Apocalypse.
After half a month's efforts, the mutant nests in the west side of Wanghai were cleared out. Other than that, NAC soldiers built eleven inspection stations along Huangpu River to block all bridges that connected the west side of the city to the east side to prevent mutants from spreading to the west.
All the mutant nests on the west side of the city, whether on the surface or underground were all eliminated by NAC soldiers and mercenaries. Although creatures such as mutated cockroaches and rats were hard to remove completely, the more hostile mutants such as zombies, Roshans and even Death Claws were completely extinct from the west side. Due to the force of the NAC, the survivor groups in the area were all incorporated under NAC's control.
