"There is no paradise for those who flee."

[Halo]
The first massive circular offshore complex 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 desalination, and large hydroponic rooms.

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

[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 inside Halo despite being cut off from the outside.
Years' worth of resources are stored in the power/desalination facilities of the lower sectors, and the supermarkets 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.
Living up to its reputation as the 'Only Paradise for Humanity' praised by the whole world, the upper central plaza under the sunlight pouring through the glass ceiling was filled with its usual peaceful and glamorous atmosphere.
Until those things appeared.

Bizarrely shaped creatures suddenly infiltrated through the pipes.
Revealing blood-red saw-blade exoskeletons, they began to burst out from 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 members who rushed in with gunshots, it took only 44 minutes for the upper and middle levels to turn into a horrific mess under the spreading attacks of the Corrupted.
[Warning. Inflow detected 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 sound of something wet and non-human growling low leaks through the door crack.
The surviving humans each gripped their weapons and hid beneath the red emergency lights.
