Call-In takes place a few hours after the citadel was destroyed by Gordon Freeman.
You take the role of a rebel soldier on a mission to retrieve information regarding the
super portal to aid in the building of Dr. Magnussons rocket.

This mod was made by me Ludvig Kallin and I am happy with the way it turned out.
I started this project primarily to learn mapping about 1 year ago and what really got me interested was the mod Minerva which you can find here on mod db.

I want to thank everyone who already played and have given their comments on my work! It is much appreciated and I will surely release other games or mods in the future so the feedback will not have gone to waist.

If you are listening to the same music as you were yesterday. Why not listen to the Interview I had the pleasure of having with Phillip.

We talk about the mod and discuss parts that many have criticized as well as combine architecture.

This was pretty good. I liked the environment transitions that you made: even though they happened really quickly, they seemed natural.

Actually, this is probably an episodic Modification only just done in one chapter, Developer don't want to tell all about that what a cheap-*** bastards.

Just Joking, this modification is great hopefully, waiting for another one to be done in no time.

Really enjoyable - "A scene can rapidly change, from lush forest environment to water logged sewers without a logical explaination" makes no sense, everything fitted together!

While to cramped for large numbers of players, I think you should consider porting this to Obsiden Conflict when the new version comes out.

Well, after you destroy the helicopter, you have to go into the building that's on the platform. Pull the lever in the building, and then keep going with the airboat.
