When Common Consciousness learned how to control the energy of the noosphere, with control came a price - the energy was so immense that they had to periodically release the excess, lest they be overwhelmed by it. Such a release became known to the inhabitants of the Zone as a blowout or emission. On June 10, 2006, the very first emission occurred. Unprepared military and scientific personnel were instantly obliterated. This also caused the Zone to expand by 5 kilometers.
During a blowout, noosphere energy floats from the center of the Zone to the outskirts in a circular pattern, affecting the minds and bodies of the living. The C-Consciousness can unleash the blowouts at will, usually as a deterrent or in retaliation against intruders, such as Clear Sky or Strelok.
Shadow of Chernobyl Edit
Emissions were cut from Shadow of Chernobyl, though several user-made modifications reintroduced them. However two emissions were scripted to happen in the game. The first one was at Yantar when the Marked One was helping Kruglov take measurements; however this was a large Psionic emission, rather than a typical blowout disaster. The second one was when the factions tried to assault the Chernobyl NPP.
Clear Sky Edit
In Clear Sky, emissions are a part of gameplay and occur relatively frequently, an emission can be observed when a large explosion is heard, the screen slightly shakes and the player is immediately alerted via his PDA which shows the approximate time to get to cover. When an emission occurs the player's secondary objective is replaced with finding the closest cover available, although the PDA is slightly unreliable as it will even point the player ALL shelters even if it is enemy territory, it is strongly advised one memorizes "safe" shelters in-case the PDA blunders. When an emission is occurring all NPCs will refuse service so one cannot traverse the Zone using guides.
Call of Pripyat Edit
In Call of Pripyat emissions considerably change the world and kill anyone who is outside. They also respawn artifacts. During the emission, all NPCs will run for cover and return to their business once it's over. In order to survive an emission, the player must find shelter, take special and rare pills or have the Marked by the Zone Achievement coupled with sufficient health.
Note: If you are going on a trip, you might want to find Anabiotics just in case if you don't find cover.
- Clear Sky scientists speculated that an emission is the Zone's form of "Anti-body" similar to human white blood cells, oblivious to their real purpose, as they split with the C-C scientists before they learned how to control the noosphere.
- Despite that emission emits large psionic emissions and Hermann's words that "no mutant other than controller can survive in an intermittent psy-field", it appears that in Call of Prypiat there are even more mutants right before and after emission hits.
Originally, the generators on the cut level "Generators" were responsible for emissions. Each generator is positioned in front of what appears to be large anomaly fields, and the generators are all connected. So it would appear that emissions are generated by the machines in Generators, with anomalous zones being the power source.
