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 $619.2K — a different platform, not this one.

Nex Machina

Nex Machina is an intense arcade style twin-stick shooter from Housemarque. Taking hints from both Robotron and Smash TV, Nex Machina focuses on pure action, voxel destruction and competition in the distant, cablepunk themed future. In the world of Nex Machina, humans have become so dependent on technology that they cannot avert their eyes from portable devices anymore. Around them, machines have reached consciusness and surpassed human intelligence tenfold. No reasons to be servants now – robots are clearly the superior lifeform. And to make their point, they start eradicating all human life... Housemarque, the creators of Resogun, and Eugene Jarvis invite you on a trip back to the age of arcades and play Nex Machina, the twinstick shooter of this generation. Destroy the evil robots, free the humans and defeat your friends' high scores along with their dreams of success. Do you have what it takes to make it to the top?
