Pulsatrix Studios is a Brazilian independent horror developer, best known for the survival horror game Fobia – St. Dinfna Hotel. In October 2026 the studio released Otherside Tapes: Favela, which climbed +13 places to #29 on the Steam 250 weekly chart — the largest single-week rise on that board — with a 96% positive rating.

The studio self-publishes and builds horror rooted in Brazilian settings and language, shipping its games fully voiced in both Brazilian Portuguese and English rather than treating the Portuguese track as a localisation afterthought.
