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 $31.7K — a different platform, not this one.

Signal Ops

As an officer in the shadowy halls of Facility 7C, you remotely lead a squad of operatives on daring espionage missions. Plant evidence, steal secrets, assassinate targets, and performing sabotage for the glory of the Dark Father. Do you have enough faith to follow orders unquestioningly? Take advantage of multiple simultaneous first person views to stealthily evade enemies or get the drop on them. With the shoddy equipment and dubiously trained agents provided to you, you’ll need all the advantages you can muster. Signal Ops blends elements of a tactical shooter, stealth, and strategy to serve up a concoction that will satisfy your refined gaming palate. With open levels, old-school sensibility, and a monitor bank blasting a full spectrum of possibilities onto your retina, Signal Ops is unlike anything you’ve played before. Simultaneously see the first-person perspectives of your whole squad. A squad shooter with stealth and espionage elements set in a dystopian society. Select agents and weapons for your squad to suit your play style.
