Devolver Digital and developer Croteam have confirmed that Serious Sam: The Third Encounter is in development for PC, accompanied by a teaser trailer and a Steam page now available for wishlisting.
The new title is billed as a direct sequel to Serious Sam: The First Encounter (2001) and Serious Sam: The Second Encounter (2002), and the team says it will return the series to the early-2000s timeline rather than follow the narrative path of later entries.
What the announcement says
The reveal positions Serious Sam: The Third Encounter as a reboot to the franchise’s signature run-and-gun action.
Promotional messaging emphasizes a revival of the series’ “non-stop carnage,” combining a mix of classic weapons from the original games with newly designed armaments.
In journalistic terms: the publisher framed the project as a deliberate return to the franchise’s bullet-hell roots, promising expansive alien environments and an arsenal that pairs familiar tools with new additions as players take the fight to the antagonist known as the Notorious Mental.
Developer and platform details
Croteam, the studio behind the original Serious Sam games and the most recent entry, Serious Sam 4 (2020), is leading development.
Devolver Digital is listed as the publisher on the Steam page.
The announcement explicitly covers development for PC and the Steam storefront; a release window was not provided.
The Steam product page has been made available for players who want to add the game to their wishlist.
Console and release outlook
No confirmation has been given about releases for consoles or platforms such as Nintendo Switch, and there has been no Nintendo Direct or eShop announcement regarding the title.
At present, PC (via Steam) is the only platform listed publicly.
Series context and next steps
The Third Encounter marks a return to the era that first established Serious Sam’s identity in 2001–2002, following several subsequent sequels and ports across platforms.
Interested players can visit the Steam page to wishlist the game; Croteam and Devolver Digital have not yet shared a release date or a broader platform rollout plan.
