About the game

ISO/2004 is a grounded psychological horror game about guilt, trauma, and disturbing memories rotting inside a decaying provincial home. Step into a suffocating, atmospheric nightmare where raw emotional tension slowly warps reality. Face what you left behind before the shadows consume you.
