Dark Interval is a campaign mod created as an alternate take on Half-Life 2, incorporating selected early story drafts and cut content. We're creating new maps, assets, characters and story beats to fill in the blanks, and to build a coherent story of its own. The mod is released in episodes, the most recent being Dark Interval: Part I - an intro chapter to the bigger picture.

Bad news, good news

News 16 comments

Bad news: despite our earlier promises to release DI Part 2 as 17 maps going from Kleiner's Lab escape to the Depot, the first release will only contain the first 12 maps. It's either this, or never living to see Part 2 release at all.

This also means that Haven and Beach maps from the Wasteland Demo (available on our Discord) won't be included in the first release. Why? Because there are three more maps between them that are not completed.

Good news: we have a release window. And the trailer.

The mod is out of alpha, and in the next few weeks it will enter the final closed beta test, where we'll find and fix bugs, make final adjustments to gameplay and item balance, finalize all the story scenes. How long it will last depends on how many problems we find and how fast we can fix them.

Additionally, Part 2 will include all maps from Part 1, but they won't receive drastic changes on release.

Do I install this like any other mod by unzipping it & putting it into sourcemods folder? Will i need to install source sdk or anything?

You must put it into sourcemods, have SDK Base 2013 Singleplayer installed and set that to the upcoming beta branch. This is all mentioned in the included readme.

Love the part 2 demos. The wasteland has always been my favorite chapter, and you guys have done the best version of it to date. Keep up the good work!

Will you recreate sand barnacles for the wasteland?

We don't feel like embarking on the path of designing the sand barnacles.

Amen to that. The sand barnacles would be ******** because they would be on the ground and blend in with the environemnt.

That's the whole point of them, blending in to catch prey.

I can see the huge effort u guys been putting in this mod and i cant wait to see the full release! and also i have a question, so when it comes to characters that appear in retail and beta like Alyx are you planning for a voice actor to voice it or using an AI voice tool?
