"There is no paradise for those who run away."

[Halo]
Humanity's first massive circular offshore complex city, built in the middle of the Pacific Ocean in 2050.
A self-sufficient giant artificial island and a perfect ark equipped with geothermal and wave power, seawater purification facilities, and large hydroponic cultivation rooms.

[Corrupted]
New mutated monsters of unknown origin.
They possess bizarrely elongated joints, blood-red skin, and saw-blade body structures.
They lack intelligence but are extremely sensitive to sound and vibration, preying on living creatures indiscriminately.

[Alpha Team & Beta Team]
Private security special forces responsible for Halo's public safety and facility security.
Though heavily armed, they prioritize high-level orders and control of key resources over protecting survivors since the incident, leading to internal conflict (Kwon Muhyeok vs. Ji Eunseol).

[Looters]
A faction of civilian survivors in sectors that became lawless after the lockdown.
Led by Tak Jekyeong, they use force to ruthlessly seize survival resources such as food, medicine, and weapons.

[Self-Sufficient Survival System]
The reason long-term survival is possible within Halo despite being cut off from the outside.
Years' worth of resources are stored in the power/purification facilities of the lower sectors and the hypermarkets and storage warehouses of the commercial district.

The year 2050,
A massive artificial ark rising across the horizon in the middle of the Pacific Ocean.

Cutting-edge self-sufficiency technology, hydroponic facilities, artificial beaches, and perfect security.
Befitting the title of 'Humanity's Only Paradise' praised by the world, the central plaza of the upper level was filled with its usual peaceful and glamorous atmosphere under the sunlight pouring through the glass ceiling.
Until those things appeared.

Bizarrely shaped creatures that suddenly infiltrated through the pipes.
Revealing blood-red, saw-blade-like exoskeletons, they began to burst out everywhere.
"G-Guard! Where are the armed guards?!"
"Aaaagh! My leg, my leg!! Help me—"
Screams, the smell of blood, and furniture being trampled.
Despite the fire from special forces who rushed in with gunshots, the Corrupted's attacks spread like wildfire. It took only 44 minutes for the upper and middle levels to turn into a horrific shambles.
[Warning. Inflow confirmed in lower sector pipes.] [Activating emergency lockdown protocol.]
As mechanical warnings echoed throughout the building and external escape routes were sealed, the paradise turned into a sealed prison ruled by blood and silence in just a few minutes.
Before long, from beyond the blood-stained corridor, the low growling of something wet and non-human leaks through the door crack.
The surviving humans each grabbed a weapon and hid beneath the red emergency lights.
