ENTER THE QUARANTINE

Hazard Protocol is a 1–4 player top-down cooperative horror shooter built around short, tense missions. Enter abandoned hospitals, research facilities and quarantined city streets as an outbreak-response operative. Complete the objective, keep the squad alive and reach extraction.

FIGHT AS A SQUAD

Stay together, cover different angles and rescue downed teammates before the infected overwhelm your position. Special infected leap, spit acid, ambush and break apart a careless formation. Ammunition, grenades and medical supplies are limited, so every mistake follows the squad into the next room.

OBJECTIVES UNDER PRESSURE

Restoring power is only the beginning. Unlock sealed doors, find access cards, operate keypads, redirect steam and solve environmental mechanisms while the horde closes in. Some objectives split the team; others force everyone to defend the same exposed position.

A DIFFERENT RESPONSE EACH TIME

Encounter pacing adapts to the squad's condition. Enemy pressure rises and falls, selected layouts and routes change, and resources do not always appear in the same place. Four difficulty levels change enemy health and damage without turning the mission into a different game.

BUILD YOUR OPERATIVE

Choose an operative and their default kit, or customize your primary and secondary weapons from unlocked equipment. Earn account XP after every mission, unlock new side-grade weapons and passive perks, and equip up to three small bonuses. Progress expands your options without replacing teamwork or skill.
