Zombie Master's Gilman city remastered by me using Global's V3 as a base.

Gm_gilmancity is a zombie invasion map, where your goal is to survive as long as possible. Start the zombie invasion by using the radio in the main house and stop it by using the smaller device next to it at any time. If you prefer to just explore the place or put your own npcs, don't use the radio. The map doesn't give you weapons, so you have to spawn those yourself, but you'll find a lot of ammo around. The map has music tracks, which do get affected by the music volume. Make sure you turn music volume up if you want to hear them. There is also a dev room under the main house if you need the music off.

The map has navmesh and ai nodes.

What does this remaster include compared to the previous versions?

● The ability to stop the zombie invasion without cleaning up the map. ● Rainy day, night and nightmare version of the map. ● More enterable buildings! ● Difficulty increases as you play (survive an hour and experience the bloodmoon difficulty alongside with it's tense music). ● More interactable objects and events. ● Previously inaccessible sewer pipe is now accessible. ● Added zombine. ● AFK room for your friends when they have to use the bathroom. ● Clipped stairs. ● A lot of details added everywhere, 3D windowsills, more soundscapes, improved lighting, redone brushwork and custom made props, skybox improvements with moving clouds and dynamic weather effects (ex. thunder, bloodmoon) Turned most prop_dynamic entities into prop_static ● Friendly Alyx shop owner and her clone friend.
