About Not My Son
Not My Son is a first-person horror game about a man who has just married and is left alone with his wife's son for the first time. The boy rejects him from the start. He watches, he judges, and he seems to know more than he should.
At first you try to act like a family and brush off the odd moments. Then the boy gets worse and the house starts to feel wrong. You explore it room by room and find pieces of the past that explain what's going on.
It's a walking simulator with no combat, and it takes about 45 minutes. Antantic released it on Steam on 5 November 2026 for Windows, at £2.99. The developer's post about the cake his wife made for the release got 3,729 upvotes on r/IndieGaming.
