Description
I am happy to say that gm_Underground_IV has been rereleased on Garry's mod, with several big improvements!
The map requires Half Life 2: Episode 2 and Half Life 2: Episode 1 to work properly, if you don't have them installed and mounted, you will have tons of errors.
I have worked for a very long time on this map, and while it's been released, I will continue to make bug fixes and small additions as I hear feedback.
Features:

Large underground military base with several different sections.
Surface level set in an abandoned wooded area.
Working Missile silo.
Buildings for Role Play.
NPC nodes.
Several operatable blast doors.
And more stuff I can't list here!

I hope you all enjoy this map, if you do, please give it a like and favorite it! Also check out my other maps and my group, TripleAMaps.

Also, if you're going to host this map on a server, tell me about it, I'd love to play!

To open the missile silo, and fire the missile you have to find the control room in the lower section of the base. In there is a green switchbox from Dr. Kliener's lab in hl2. Open it and pull the lever activating the alarm, once you've done that, you will see two previously unit screens turn red in the control room with a message to enter launch keys. Under each screen is a button that will be glowing red, press both of them until they turn green, and the missile will launch after 10 seconds.

You MUST have Half Life 2: Episode 2 and Half Life 2: Episode 1 installed on your computer.

Cheese Curds you have to get half life 2 episode 1 and 2 on steam and download them, Gmod will then load their assets into the game
