The night had darkened, like a curtain of mist.
From a high altitude, one could see that zone E3 had plummeted into absolute darkness, without even the artificial moon projected in the sky.
Inside the E3 zone, the city's broadcast repeatedly played the same message over and over:
"E3 zone has suffered a terrorist attack. T2-level 'Black Boots Hunter' program malfunctioned and is now releasing poison gas indiscriminately, killing civilians. All residents, please stay indoors, do not go out, turn off all lights, keep silent, and wait for rescue."
"E3 zone has suffered..."
The synthetic, mechanical sound echoed unceasingly above E3 zone and after a prolonged repetition, this sound became like some sort of meaningless spell, intensifying the panic and repression among the residents of E3.
The zone was left with only the broadcast and the occasional sounds of gunfire, explosions, and screams.
