Standard Protocol
Six tasks plus the four computer files open the gate, and it stays open. The classic way to learn the maps and the killers.
FREE ONLINE CO-OP HORROR
The night picks a killer.
You pick how to escape.
Play alone or with up to three friends, complete the map’s tasks and open the exit before the hunter finds the group. No download, no install — just press play.

Explore the village, complete six tasks, recover the four files and open the gate. Footsteps and your heartbeat warn you when the killer gets close.
SURVIVAL PROTOCOL
Pick a survivor, a map and up to three items to carry.
Complete tasks while the killer tracks noise and wounds.
When the gate is free, run. Falling in the match costs you your equipment.
THREE WAYS TO SURVIVE
From the classic protocol to a blackout with fire and a captivity with cages: the host picks the mode before the match starts.
Six tasks plus the four computer files open the gate, and it stays open. The classic way to learn the maps and the killers.
Every station becomes a generator. Six generators and the four files only unlock the lever; winning the lever minigame opens the gate, and from then on you have two minutes to get out while the fire spreads — in the last 45 seconds the smoke drains your health. Failing a minigame here gives your position away to the killer.
Bring the power to 100% with six generators and keep them running: each maintenance stabilizes a unit for two minutes. The first hit wounds you and the second locks you in a cage; teammates free you by beating the lock. You lose when every remaining survivor is caged.
A co-op mode with no killer: up to four survivors enter the Veradon Institute, a clinic hiding a clandestine lab, and the cave beneath it. Restart generators, open doors with keycards, copy the evidence to a pen drive, descend into the Rift, defeat Specimen Zero and escape through the drain. Firearms, melee weapons and scarce ammo; a downed teammate can be revived. Content warning: intense violence and blood.

ABOUT THE GAME
Horror Intense is a free online co-op horror game that runs in any modern browser, on computers and phones. Up to four survivors team up against one killer — a friend playing online or the AI — across four haunted maps: a cursed village, an abandoned hospital, a foggy downtown with a subway and a school swallowed by the woods.
Each match is short and tense: repair and search at the task stations, read the computers to find out who is hunting you and what his weakness is, and escape through the gate. Thirteen killers with their own powers and senses, fifteen survivors with six archetypes and three game modes make every night different.
There is nothing to download and no account is required to play. Create a room, send the code to your friends and survive together — or play solo with bots to learn the maps first.
