Winter, 1962. A research installation deep beneath Eastern Europe goes silent.
The record ends there. The rest, you'll have to find for yourself.
The Echo Engine runs on technology developed entirely in-house: a custom C++ engine written from the ground up for physics-first horror. Real-time dynamic lighting, a full rigid-body simulation at the core of every interaction, and levels authored in an industry-standard brush workflow. No licensed engine. No shortcuts.
A multiplayer co-op modification for Frictional Games' Penumbra: Overture, built directly on the HPL1 engine. Two players. One nightmare. Surviving the mine was never meant to be done together — until now.

Quasi Interactive was founded by Nicolas Balkhausen — a passionate gamer and creative who has dreamed of making video games for as long as he can remember.
It started at age five with a controller in hand and Ocarina of Time on the screen. That world cracked something open — a love for games that never faded. Years later, discovering Cave Story by Pixel proved that one person with enough vision could build something extraordinary. That revelation became a mission.
Games like SOMA and Dark Souls shaped what that mission looks like. Both prove that atmosphere and environment do the heaviest lifting — a place that feels real, oppressive, and alive is scarier than any cheap jump scare will ever be. That's the kind of horror Quasi Interactive builds toward.
A studio built on the belief that great things come from people who care deeply — about the craft, about the player, about every detail that separates a good game from one you never forget.
