In Quantum Error, you play as a firefighter who came to rescue people from a burning research complex. As it turned out, quantum technologies were being studied at the facility, and, obviously, some experiments did not go according to plan. The complex has been captured by a dark entity that brutally kills people. You have to save the remaining survivors and destroy evil.

Gameplay Quantum Error is a bit like Doom 3. As the developers themselves stated earlier, this is a “space” shooter. Although the complex is located not far from San Francisco, at some point the main character will move outside the Earth. In order to survive in the quantum chaos, the firefighter – Captain Jacob Thomas – will need to master weapons and fight demonic creatures, as well as use rescue tools such as an ax.
