Players get a closer look at some furry headcrabs and a discarded shotgun as a feminine voice speaks of a tunnel to Ravenholm. “We don’t go there anymore,” she cautions, “Believe me, that tunnel is sealed for a reason.” The trailer concludes with an apparent title drop, reading “Project Borealis: Prologue,” anda tentative release window of Fall 2024.

What Is Project Borealis, And How Does It Relate To Half-Life 2?

Everything We Know About Project Borealis So Far

Project Borealispicks up whereHalf-Life 2: Episode Twoleft off: on a cliffhanger ending that has yet to receive any kind of official closure. Two years after the release of theHalf-Life 2base game in 2004, Valve began putting out short, episodic sequel chapters, beginning withHalf-Life 2: Episode One. These would directly continue the story ofHalf-Life2;Episode Onebegins immediately after the destruction of the Citadel core, as Gordon and Alyx aid in the evacuation of City 17.

Recent Update Points To Major Half-Life 2 Overhaul That Could Make It Worth Revisiting

As Half-Life 2’s 20th Anniversary nears, a quiet update suggests that Valve may be planning a major celebration for its iconic first-person shooter.

It was followed again byEpisode Twoin 2007. This chapter portrays a rebellion by the inhabitants of City 17 against the Combine, and ends on a mysterious note. ThroughoutEpisode Two, Gordon, Alyx, and their allies seek theBorealis, a long-missing Aperture Science research ship and the purported location of the vanished Judith Mossman. At the end of the game, Gordon and Alyx prepare to depart for theBorealis, only to be subject to a sudden Combine attack that claims Eli’s life and leaves Alyx grieving.

The Aperture Science corporation appears prominently in thePortalseries, so it’s likely thatHalf-Life 2: Episode 3would’ve united Valve’s two major sci-fi properties.

There was, of course, a planned third part to the trilogy, but it has since become one of the many canceledHalf-Lifeprojects to disappear into the ether.Half-Lifewriter Gary Laidlaw later posted a short story entitled “Epistle 3” on his website, which is often presumed to be his scrapped plot outline forEpisode Three. Laidlaw himself has denied this, butProject Borealisuses the content of this short storyas a basis for its plot.

Therefore, it’s likely thatProject Borealiswill see Gordon and Alyx finding the titular Aperture ship, and discovering that it was used to research interdimensional travel. Its systems malfunction, and the two find themselves lost in time as they struggle to gain control of theBorealis, and find a way to weaponize it against the Combine.

This 9/10 Steam Game Is The Closest Thing To Half-Life 3

Players have been waiting for Half-Life 3 for decades now, and although it may never come, VLADiK Brutal might be the closest thing to it.

However, what’s being advertised in the teaser appears to be a mere prologue, with the protagonists traveling through a perilous, abandoned tunnel towards theBorealis. The first part ofProject Borealisis due out this fall, but it may be some time before it gets to the meat of the story. Still,Half-Life 2fans are so starved for content that this sudden resurgence is nothing short of miraculous.
