Steam has launched a special event dedicated to fans of investigation games. Until January 19, 2026 at 10 a.m. PTthe platform offers more than 24 free demos of popular investigation games. The principle is simple: download, play, explore mysteries and, for those who are interested, consider purchasing the full version.
This type of initiative is rare in its scale. Usually, demos can be counted on the fingers of one hand, but this time, Steam highlights a wide variety of titles, ranging from narrative classics to more eccentric experiences.
The essential demos to discover
Here are some of the free investigation games to try during the Steam event:
- Detroit: Become Human – Narrative dive into a future of androids and moral choices
- The Case of the Golden Idol – Non-linear investigation and original puzzles
- Strange Horticulture – Exploration and mystery around a plant shop
- Blue Prince – Critical favorite of 2025 for its immersive plot
And this is only the beginning: Steam indicates that there is more than 50 different investigation games with demos available, offering a diversity of experiences for all mystery lovers.
Steam Bonus: mystery items in the Points Shop
Steam doesn’t stop at demos. To further enrich the event, the boutique Steam Points proposes three limited time items on the theme of mystery:
- A mystery animated avatar
- A detective themed setting
- A sticker to collect
These items do not cost real money but require Steam Points, which players accumulate by purchasing games and participating in the community.
Why this event is important for players
The interest of this event goes well beyond the temporary free admission. It offers a real showcase for atmospheric and narrative games, genres often under-represented compared to AAA blockbusters. For gamers, it’s an ideal opportunity to try out unknown titles, test before you buy, and explore diverse stories, mechanics, and creative visions — without any financial commitment.
