Sign in to your TheGamer account Half-Life 3 has long since grown to mythological proportions over the years, with countless rumors and gaming events hyped as the first-ever reveal for the new title. While most of these leaks and rumors have rarely ever amounted to anything, the past few months have seen more than their fair share of credible reveals for the third entry in the dystopian sci-fi series thanks to the 12TB Steam leak. While there's still no telling when we'll actually get to see Half-Life 3's existence officially acknowledged by Valve, some users have recently discovered even more assets from an ancient build of the original Half-Life 2: Episode 3. New Half-Life 3 Map Backs Up Ancient Concept Art Although several Steam news accounts like Gabe Follower were quick to share the discovery, one of the clearest photos was posted by Scolcer on X, allowing fans to see the sheer scale of the environments that would have been in store for players if the 2013 build of Half-Life 2 Episode 3 had ever been released. While there was some confusion over what assets included in the recent discovery were actually from Half-Life 3 or Valve's canceled sci-fi MMO Stars of Blood, especially given the Combine-like design of the ship included in the map, fans have managed to narrow it down to the spacecraft designs being from Stars of Blood, while the map itself is almost certainly from the unreleased Half-Life 2: Episode 3. Half-Life 3 Isn't As Unrealistic As You'd Think As if the massive mechanical pillars from Half-Life weren't enough of a clue, the snowy map matches up perfectly with the concept art and early asset reveals from the canceled Half-Life 2: Episode 3, which would have seen Gordon and Alyx traveling to the Arctic to investigate the dilapidated Borealis research facility. While we'll likely never get to see this version of Half-Life realized, that doesn't mean the project has been canceled just yet, as several rumors and even a recent leak by a Valve employee suggest that some form of Half-Life 3 is still in development under the codename Half-Life X. Even though it's unlikely, the heavily rumored project could wind up reusing similar concepts like the ones fans are still discovering to this day from Half-Life 3's 2013 build, well over a decade after its predecessor's.
