Nuke Pack 4
DISCLAIMER: If you have any problems with this addon, it’s likely some kind of conflict. Try disabling some other addons you have. Beyond that I can’t help you, as my own installation works perfectly and I cannot reproduce any of the issues that have been reported.
Press the use key (E by default) to arm the nuke and smash it to the ground to set it off. It also has wiremod inputs. Spawning the nukes requires admin permissions on a server, so you’ll need make other players admins via users.txt. See: https://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index0c18.html
I did not make this, I only fixed it for Garry’s Mod 13. Credit (as far as I know at least) goes to RayFan9876, Teta_bonita, Hamster, fehic and Doomsale. I also made the entities save Wiremod connections in dupes, and added Wiremod inputs to TNT. NOTE: You need Counter-Strike: Source for some of the models.
