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.

You may want to re-upload that to Mod DB since the file is gone from the link you gave.

This mod isn't updated o the latest SDK format. So it will give a lot of "error" objects and purple/black checkerboard textures.
Mod maintainer must update.

I just realized this mod disappeared from my game library, but when I looked in my source mods folder it is still there.

A handful of other mods won't appear either. While I fixed a few by redownloading them, I can't do the same for Call-In, nothing is making it come back.

Is anyone else having this issue? And is there a solution?

Reinstall, because that probably means that the textures are missing.
