GIGAH|RUSH

Browser survival horror / ARPG shooter inside a huge concrete apartment block.

GIGAH|RUSH is a free HTML5/WebGL browser game about expeditions through a self-rearranging Soviet-style concrete megastructure. You start in a safer living area, prepare food, water, ammo, medicine, documents, weapons or PSI tools, then follow a quest, rumor, contract or faction lead into hostile floors.

Every trip asks the same practical question: what can you carry in, what can you bring back, and what happens if the floor changes before you return?

The active floor is a living simulation surface. NPCs trade, sleep, fight, hide from Samosbor and can die permanently. Factions react to your actions, zones can change control, prices can shift, caravans move resources, and consequences remain through browser saves as dead bodies, empty containers, marks, rumors and reputation changes.

The central disaster is Samosbor. It can arrive with warnings and sirens: doors seal, fog leaks through cracks, monsters become active, shelters matter, and parts of the current floor can change after the alarm ends.
