Strange City
I made this map in early 2020 so it’s pretty terrible. I have published it for the purposes of preservation.
Features:
-Lots of weird things to find by exploring.
-Lots of idle NPCs have scripted sequences that will play out.
-Civilians and police walk through the streets.
-If you kill civilians or police you will be attacked by increasingly-difficult waves of Combine.
-You can break into the general shop and be attacked by its owner.
-You can kill the mayor of the city for harder enemies to spawn.
-There are a bunch of portals and hidden areas.
The map can be found in Other under "gmodmap1".
