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.

Project Warlock

Project Warlock is a first person shooter that fans of Doom, Hexen and Wolfenstein cannot miss. It serves you an exploding cocktail of bullets, spells and monsters. In Project Warlock you battle through 60 levels of non stop action packed with bloodthirsty enemies and challenging bosses. The game offers not just firepower, but perk-based character development, weapon upgrades and unlockable spells system. This high-quality independent gem is priced to appeal to fans of polished indie titles and seekers of classic fps experience alike. Back in April 2018 hundreds of gamers had a chance to experience an early build of Project Warlock and gave their enthusiastic feedback. The following six months the Buckshot team, with it’s showrunner Jakub Cislo, spent on polishing the game to bring you the most complete and satisfying experience. The end result is something you can check for yourself. Oh. And John Romero thinks “it looks cool”. Features 60 levels 5 worlds 72 enemies 38 weapons 8 spells 12 perks
