Something Seems Horribly Wrong With Your Sibling In My Big Sister


My Big Sister explores sibling love and an eroded mind, following Luzia as she tries to bring her sister home throughout this horror adventure. However, something seems quite off about the older girl, which players will come to know all too well.


My Big Sister aims to offer a psychological horror experience, delving into questions surrounding Luzia’s sanity as players dig into her dreams and her attempts to help her older sister, Sombria. As players move through the story, finding items across an ever-shifting landscape and using them to solve discomforting puzzles, they’ll uncover a bloody tale and a sibling love that persists beyond it. In the end, players may have their answers as to what Sombria has become, and why her sister is still looking out for her.


My Big Sister is available now on Steam Early Access. A demo is also available through
