Grottopolis (Sandbox)

Contains Ground and Air NPC AI nodes, Combine Helicopter/Gunship/Dropship Flight Pathing, and a Navmesh
LDR and HDR Compatible.

This is a sandbox map, working well for NPC battles, with 2 unique additions. These are :

  1. A toggleable broadcast in the center of the map (starts disabled to help with performance), courtesy of an interactable camera which circles the map.

  2. When anything falls far below the map, it is teleported to a corresponding position far above the map, instead of being destroyed. Physics objects will infinitely fall if nothing gets in the way!

The map is set in an abstract environment, suspended within a void, itself consisting of several interweaving platforms.

There is a secret room near the bottom of the map to toggle the teleportation mechanic, if need be.

I hope you enjoy!
