This tutorial will teach you how to add a Survivor NPC who will use a mounted gun to kill infected that come within it field of fire.
{{note|Louis is the only bot capable of using the mounted machine gun.}}
{{tip|Instead of doing it yourself, you can download [https://github.com/Mrfunreal/Prefabs/blob/main/Maps/l4d1_bot_npc_spawn.vmf this prefab] and copy paste its content into your map}}

==Construction==
===Making an Emplacement===
#Create an emplacement for your mounted gun. All Survivor NPC's will not take damage and do not interact with survivors or infected. Having this emplacement accessible to zombies will interfere with suspension of disbelief.<br>Consider placing your mounted gun in a location that appears inaccessible to common infected to hide the NPC's invulnerability.
#Add a {{ent|prop_mounted_machine_gun}} to the emplacement. Ensure you have the right gun. Neither {{ent|prop_minigun}} nor {{ent|prop_minigun_l4d1}} will work in this situation.
#Add an area for the NPC to spawn in. If you want the survivors to see the NPC walk to the gun, ensure they cannot see the NPC when it spawns, as it will appear out of nowhere.
===Adding the NPC===
#Create four {{ent|info_l4d1_survivor_spawn}} where you want the NPC to be created. Set their "Character" field to your desired bot. Name all four {{ent|info_l4d1_survivor_spawn}} "L4D1_Bots".
#Create four {{ent|prop_dynamic}} nearby, using the L4D1 player models. This is done to precache the models.  Name all four {{ent|prop_dynamic}} "L4D1_Models".
#Create a logic_auto. (Any entity capable of firing outputs will work)
Set its outputs as follows:
{| {{OutputsTable}}
| [[File:Io11.png]] || OnMapSpawn || L4D1_Bots || SpawnSurvivor|| || 0.00 || No
|-
| [[File:Io11.png]] || OnMapSpawn || L4D1_Models|| Kill|| || 0.01 || No
|}
