Have you ever been in a battle for a hl2 map, and enemies continously spawned and you have no idea where there coming from? The NPC_template_maker can do just that, by changing some of its options, you can make NPC's spawn from one of several info_npc_spawn_destination points around the entire map. I usually put in an AI_GOAL_FOLLOW just to help the NPC's find there way to the player, hope this helps
It's a bit tricky retriggering an assault every time they are spawned.
Nice example!
Nice example! I will use it sometime.
