Launch forecast
Estimate how many people will play this game at launch
A strategic, narrative horror roguelike. You've been given a briefing on Site-19. Most of it is ████. You'll investigate anomalies you wish you hadn't, fight what you couldn't prepare for, and sacrifice more than you planned. Then you'll start a new story. Maybe this time you'll know better.
