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 $7.2M — a different platform, not this one.

Door Kickers

Door Kickers is an innovative real-time strategy game that puts you in charge of a SWAT team and lets you command them during a tactical intervention. Analyze the situation, plan team routes, choose equipment, breach points and coordinate multiple troopers to reach the hostage room before the bad guys get to press that trigger. It may sound daunting, and like real world CQB combat, it sure is. But most levels can be completed in minutes, and on the fly improvisation works. Achieving the perfect plan for getting the mission done with no false steps; that is a skill not easily mastered. 2D, Top Down for optimal tactical analysis Real time with free pause No turns, no hexes, no action points or awkward interfaces Realistic and action packed Non-linear levels, freeform gameplay Mission editor and modability Unlimited gameplay via mission and campaign generators
