The more than two decades since Half-Life 2's release have been filled with plenty of rumors and hints about Half-Life 3, ranging from the official-ish to the thin to the downright misleading.

The latest tease came just before the end of 2024 via a New Year's Eve social media video from G-Man voice actor Mike Shapiro.
