About R.A.T.: Human Error – Episode One
R.A.T.: Human Error – Episode One is a story-driven game about a sick child trying to escape a hidden underground facility and reach their waiting mother. After a war ended in a blinding flash, survivors fled underground, where a sickness began to warp minds and bodies. The child does not know why they were taken to the facility, only that they are sick and something is wrong.
Escape the facility
You crawl through vents and follow echoes toward the surface, exploring a decaying bunker where rooms conceal secrets and objects reveal fragments of a hidden story. Vents and passages form a shifting labyrinth in which paths split, change and close behind you. Creatures stalk and listen in the silence, and there is no turning back.
Uncover what happened
Strange figures linger in the shadows. Some may help, while others deceive, and none can be fully trusted; their words can reveal the truth or bury it further. The journey branches in many directions, but each route leads toward the same revelation. What you discover depends on where you go and what you dare to see.
