Half-Life 3 Rumors Surge on New 2025 Reveal Claims as Valve Stays Quiet

One reporter says a reveal this year is likely to be a standalone announcement, not at The Game Awards.

Overview

  • Insider Gaming’s Mike Straw says a source gave him a date for a 2025 announcement but he could not verify it and believes it will not be unveiled at The Game Awards.
  • Other leakers and dataminers, including GabeFollower and Tyler McVicker, suggest Valve is aiming to announce HL3 or an HLX project soon, though timing details conflict and remain unconfirmed.
  • Valve’s Steam storefront currently shows two upcoming games while only Deadlock is visible, and the SteamDB creator has flagged a private Source 2 app ID as suspicious.
  • References to a Source 2 project codenamed HLX have circulated since May, and Valve’s recent hardware reveals for early 2026 have fueled speculation about a software tie‑in.
  • Social media buzz intensified after Geoff Keighley’s wishlist screenshot prompted theories, but he later showed the lone wishlisted game was Dadlympics, and there is still no official announcement.
