No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $1.9M — a different platform, not this one.

Skyhill

World War III was one cruel tragedy, at least for the others. You seemed to have a quite nice time, hidden in your fancy penthouse at the Skyhill Hotel... Till the impact of a bio-weapon blew away the life you once knew. Now there are mutants everywhere, and they're eager to rip you to shreds with their vicious claws. But they aren't your only problem: Your supplies are running out. You have to leave your luxurious penthouse and search for food. Walking through the skyscraper means going through hell. There is danger around every corner and death is a steady companion. But seriously, how would someone prepare for something like this? It doesn't matter anymore. Nothing matters but survival. And time is running out. • Roguelike RPG gameplay in an apocalyptic survival setting • Feels fresh every session – randomly generated maps • Gain experience, craft weapons and look for useful objects
