Half-Life 2 Episode 3 source code leak reveals more of Valve’s apparent plans for a sequel

A newly shared leak of apparent *Half-Life 2: Episode 3* source code offers clues about weapons Valve explored for the unreleased game. The findings renew interest in the studio’s abandoned plans for a follow-up, but do not indicate that a new *Half-Life* game is imminent.

The code, posted by Valve-focused account GabeFollower, appears to date from around 2008 and names the Blobulator and the little-understood Weaponizer. Valve had previously shown the Blobulator as a shape-shifting blob of mercury that could attack or trap enemies, though it could also turn on the player; related technology later appeared in *Portal 2*’s Mobility Gels. *Episode 3* was never released, and the article says Valve tried several versions of the next instalment, leaving modders to draw on the leaked material.
