Many fans expected Valve to announce Half-Life 3 in 2025, and Gabe Follower believes the news was delayed, which was the reason the second edition of Half-Life 2: Raising the Bar was postponed: he thinks the book will be out once the game is revealed.

For now, we can get glimpses of HL3 features in the updates to Valve’s Source 2 engine. Based on mentions of HLX in the code, Gabe Follower says that the game will offer dynamic physics and gravitational anomalies, where gravity no longer pulls objects in one direction but can be tied to a point, making objects’ gravitational pulls affect each other.

Characters will now have more accurate hitboxes that adjust to their limbs instead of simple boxes.
