Define Half Life 3 Meaning

A game that was confirmed 10 years ago from this very year yet is still not released.

The Game that will never exist

A game which descended from the heavens in the year 2020

The speculated predacessor to Half Life 2: Episode 3.

Though Valve has confirmed that episode three will be the last in the current story arc, they have promised that the Half Life games will continue, most likley through the "episodic medium" they are currently being delivered in.

**Speculation from the next game being the actual anticipated HL3 can be justified by noting that the plot lines of Half Life 1 and 2 are different from one another, so in Valve's admission that the series will not end at Episode 3, it can be inferred that the next title will be HL3**

One thing certain about Half Life 3 is that it will be the continuation of the greatest game ever made, aside from portal, which is tied with half life for that title.

A fictional game that many people claim to have heard announced but never came out (a case of the mandela effect)

A game that will be realased in REDACTED by Valve Corporation.

1. A game by Valve yet to be announced.
2. To describe something as highly unlikely and wanted by a lot of people.

A phenomenon that occurs when a piece of media (mostly video games) is put on hiatus or when there is a very large gap inbetween releases, where people will overhype and praise the content to the high heavens, even before release. It then either doesn't get released or does get released, causing everyone to be disappointed because their soaring expectations weren't met, that weren't very realistic in the first place.

This isn't the doings of the developers, this is the doing of the community who in an attempt to keep their hopes up, make excuses about their favorite piece of media being or soon becoming the greatest piece of entertainement ever, e.g. Half Life 3. Aforementioned hopes are then usually crushed and they go to metacritic to rate the item a flat 1 or 2.
