—In this multiplayer horror game (up to 4 players), survive the relentless monsters that track you down. Use items and monitor cameras to spot the creatures; every second counts. Teamwork and strategy are your only chances of survival… are you ready?
T.I.O.S(MP)
Steam
Playable solo or with up to four friends. You and your team find yourselves trapped in a house, where survival depends on your ability to interact with the environment and strategize.

Sound is your best ally. The monsters lurk in the shadows, but their telling noises can guide you to their locations. Use the curtains to block their line of sight and scare them away, but be careful! If a window is already open, you must act quickly to close it before it's too late.

They will force you to search the house for candles while trying to restore the electricity. To do this, you will need to either find the key to the basement door or force it open to access the necessary equipment.

You will be able to monitor the windows and keep an eye on the monsters. Each creature has its weaknesses; it's up to you to discover them to survive.
Will you be able to outsmart the horrors lurking in the house? Form your team, sharpen your reflexes, and prepare for a terrifying experience where every moment counts. Get ready for an intense adventure, where adrenaline and fear intertwine around every corner!
