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 $99.6K — a different platform, not this one.

Midnight Protocol

You assume the mantle of a prominent hacktivist, ‘Data’, who recently got doxxed and has been targeted for blackmail by a shadowy branch of government. You interact with the virtual environment through your home terminal that requires nothing more than your keyboard. > HANG YOUR [H]AT Will you respect others’ privacy and bank accounts, or leave no stone unturned? Midnight Protocol allows you to play as the hacker you want to be. Help the police track down a rogue hacker, or blackmail a desperate husband trying to recover… dubious pictures. Gain black, grey, and white hat reputation to change the direction of the story based on your choices. > I[M]MERSION OVERLOAD Midnight Protocol’s design focuses on immersing you in a world of digital warfare without complicated hacking mechanics. Your keyboard is your weapon, type commands to eliminate or evade security programs, letting your keystrokes become part of the soundtrack. > NICE [D]ECK Cracking a digital safe or extracting classified data requires careful planning. Pay the troll toll, use digital jackhammers, cloaks, and daggers to combat cybersecurity. Buy new programs or hardware on the black market, and customize your deck to fit your playstyle. > DI[S]TRACTIONS ABOUND Take on dozens of sidequests filled with easter eggs and references, gather additional intel on your targets before you start a mission, and play some hacker chess to wind down. Midnight Protocol is jam-packed with optional missions, providing hours of additional content. GL;HF
