I got my hands on O3, a haunting bullet-hell roguelike currently in playtesting, and put it to the test on the Steam Deck! Inspired by the nightmarish art of H.R. Giger and Zdzisław Beksiński, O3 throws players into a dark, biomechanical world filled with shifting rooms, deadly creatures, and intense, fast-paced combat.

In this video, I’ll showcase gameplay, discuss performance on the Steam Deck, and share my first impressions of this eerie indie title from solo developer Simion “Simy” Bogdan. Could O3 be a hidden gem in the making? Let’s find out!

If you enjoy indie roguelikes and surreal horror aesthetics, this game is definitely one to watch!
