As you might have seen in the journal entry Playbus wrote, this HL2 Sp Episode will be released very soon.
We have suffered a lot in the past few hours because of the SDK updates, but we've managed to pull through somehow.
You'll find the screenshots and preview trailer here:

We admit that the content might look like generic Half-life2 (that wouldn't be bad, would it? :P), but we assure you that there's much more lying beneath, and lots of places and situations not featured in the screenshots or the video (surprises are always good).
On top of it all, we've made sure to add replay value for those who like to explore.
Be sure to check it out in a few days!
