⚡️🔎 NEW - I don't want to get anyone's hopes up, but in the Steam Hardware video there's a "SOON™" and a sticker with an orange "H" that's covered by a censorship bar. Later in the video, the Lambda logo appears on a keyboard.
Half-Life 3 soon?

We know from datamined files that they've been working on something dubbed "HLX"
The truth is, I now believe that they are only using the Half-Life logo to promote their products rather than to release a game, because if you think about it, now that a product only has an image related to Half-Life, it sells itself.
