No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $1.6M — a different platform, not this one.

Singularity™

FIGHT THE PAST TO SAVE THE FUTURE. STOP THE SINGULARITY. Learn the truth behind a massive cover-up of the catastrophic SINGULARITY , an event that fractured time and threatens the world as we know it. Armed with powerful, advanced weaponry and the experimental Time Manipulation Device, fight enemies from the past, the present, and abominations caught somewhere in between. TIME IS YOUR WEAPON - Use the TMD – Time Manipulation Device – to change the age of objects and enemies and bend time to your will. - Age enemies to dust in seconds, manipulate objects outside the laws of gravity, and degrade objects to a withered state or renew them to their pristine form. - Unlock upgrades to harness the TMD’s full power and expand your full arsenal of advanced weaponry. EPIC SCI-FI ACTION THRILLER - Heart-pounding, first person combat action that immerses you in a world where the past and present collide. - Travel seamlessly between two eras – 1950s Russia and modern day – each rendered with stunning lighting, physics, and effects using the Unreal 3 Engine. UNRAVEL THE CONSPIRACY - Traverse the blur between the past and future in order to stop the mysterious SINGULARITY that threatens the world.
