All in all the correct terms are ' Half-Life 2 leak' or the 'playable Half-Life 2 leak' for the stolen content.

Valve does not refer to it as a leak but as a theft. These files of course include anything referred to by the community as 'Alpha' or 'Beta'. The ' Half-Life 2 leak' (or simply 'the leak'), when referring to the material stolen (or 'leaked') from Valve in 2003 by German hacker Axel Gembe, including source code, about 1300 maps, and a playable game (referred to by Gembe as 'Chosen 9').Therefore they should be taken as placeholder names referring to large periods of a game's development, 'Alpha' being used for the early stages, 'Beta' for the last stages that precede the retail release). Despite this, they are widely used across the community, as they are commonly used in the general gaming community to refer to any early stages of a video game. These terms, coined by the community and not Valve, are used incorrectly most of the time when referring to a particular subject of this period, as no development stages for any subject is known. Development stage names, such as ' Half-Life 2 Alpha', ' Half-Life 2 Beta', or simply 'Alpha' or 'Beta'.Within the Half-Life community, this period is referred to under several names. During that elongated process, many things were outlined, created and cut before the game's final release. The development of Half-Life 2 began almost immediately after the release of Half-Life, spanning from 1999 to the release of Half-Life 2 in 2004. There's an aggressive statement of this principle, which isn't entirely true but it's still interesting: It doesn't matter what we cut, so long as we cut it and it gives us the time to focus on other things, because any of the options will be bad unless they're finished, and any of them will be good if they are finished.' вЂ• Gabe Newell
