HL2 episodic achievements may be restricted to their standalone origins

In the Xbox 360 version of The Orange Box, certain achievements are shared between Half-Life 2, Episode One, and Episode Two.

• The achievements Bone Breaker, Deadly Harvest, Hack Attack!, Hot Potat0wned, Conservationist, and Think Fast are obtainable in all three games
• The achievements Grave Robber and Zombie-que are obtainable in Episode One and Episode Two, but not Half-Life 2

This ability was disabled in the PC versions of the games due to the fact that they were separate AppIDs, making it impossible to share achievements between them. But now all the episodes have been combined into the base game, making it possible to bring back the shared achievements! Considering the fact that everything is under the same Steam app now, people will probably expect these achievements to be obtainable everywhere (maybe even including Lost Coast and workshop maps?), so this is probably a good change to make.

According to the code in the SDK, enabling these achievements in all of the games should be as simple as removing the SetGameDirFilter() calls in game/shared/achievements_hlx.cpp and game/shared/episodic/achievements_epx.cpp.

Hello @vrad-exe, with With the Episodes and Lost Coast now contained within Half-Life 2 itself, we'll be reducing the visibility of the standalone versions on the Steam Store. The old standalone applications will remain available to ensure community projects that rely on them still function properly but they will now appear within the Tools menu on your Steam Library. in https://store.steampowered.com/news/app/220/view/6633333780228604001, that's a fairly clear indicator that the standalone variants of the episodic content are being sunset in favor of playing the content from the base game.

That makes this request a non-starter.

That's...completely missing the point of this suggestion. Maybe I explained badly? All the achievements are indeed now under the HL2 AppID, but as far as I am aware, the achievements I listed are still locked to only being obtainable while playing specific campaigns. They should be changed to be unlockable in all of them like on Xbox.
