The Mutation Control Center (or MCC for short) is an international institution that scans the Earth's biosphere for new species. Stations and automatic MCC beacons (or CKM beacons) are spread across the whole planet. The MCC's basic responsibilities include: examining new species, evaluating their harmfulness, and – if they prove to be dangerous – determining whether they can be separated by ABBs.
In the 1970s, nature turned against man. In addition to increasing tornadoes, hurricanes, and weather anomalies, insects began to transmit deadly diseases, and the first representative of them was a common mosquito, which during a single bite infected humans with galloping viral encephalitis.
Other insects started to mutate behind mosquitoes, and soon the birds and bats that fed on them began to mutate. Living in villages and small towns became so dangerous that global migration from smaller towns to larger ones began. A Mutation Control Center (MMC) was established, and the first primitive ABB (Anti Bios Barriers) barriers were erected. Shortly afterward, Out-Rangers, an international formation, was created to patrol the mutating natural environment.
One of the first activities of the MMC was the creation of antigravitational beacons, which were meant to monitor the area in search of mutating species of fauna and flora. It turned out that birds and bats did not like these devices and destroyed several hundred cameras. In response, the constructors installed plasma guns in them.
When megapolis separated from the aggressive ecosystem by ABB barriers were created on the city ruins, the MMC buoys were placed not only behind these barriers but also inside the polis. The MMC beacons now guard the lowest parties of the polis against aggressive representatives of flora and fauna from undercities, the ruins of ancient cities.
