3. Making the Mission

Making the mission is the icing on the cake in this guide. Go through the workshop and find a map (A Large house at Night). For a better experience look for houses that are dark on the inside.

Good Maps:
gm_shambles - Has a couple of big houses.
https://steamcommunity.com/sharedfiles/filedetails/?id=151544081
Slash Selvage - Good map for a neighborhood raid.
https://steamcommunity.com/sharedfiles/filedetails/?id=798554357
Dirty Apartment - Very detailed and messy (which is good) but not very dark (NVG will be useless)
https://steamcommunity.com/sharedfiles/filedetails/?id=550755135
Slash Lodge - Probably the best map for this scenario, big house and dark on the inside

Pull up the spawnmenu, go to options, then go to ACT3, then go to gameplay. Make sure your settings looks like this. That way NPCs will spawn with deadly weapons with random attachments.
After that, disable AI. After disabling AI, place Citizens around the house. Best placing them in rooms so that you won't get shotgunned around a hallway or something. After placing an X amount of citizens, use the command "ent_fire npc_citizen startpatrolling" without quotations and insert it in the console. Then your enemies will be in different parts of the room. A nice little touch to make things a bit harder, you can use the Extended Properties mod and make citizens panic. When they panic they will start crouching and won't hesitate to kill you still.
Once you're done placing your enemies head outside.

Get some suppressed weapons, an Assault Rifle as your primary and a Pistol as your secondary.

4. Bravo six, Going Dark

Hooray! You finished making your mission! It's best to make a save so that you can play it again. Now the time has come, the time to infiltrate the house.

Approach the house in different ways such as, using Grappling hook and jumping through the window.
Tossing a grenade inside.

Allies (Optional) - Can't do this alone? Well bring some men along with you! Spawn some combine soldiers and have them follow you. You can make them follow you by using the mod NPC Tools.

Combat - You're inside the house and there's a lot of bad guys in the area, how do you approach them? Since citizens don't have a stealth mechanic they can instantly see you and shoot you in the dark. It's best to shoot faster than they can shoot you, but try taking some cover first. It's also best if you approach corners slowly and listen to footsteps.

Clearing out Rooms - Clearing out rooms is risky. You'll never know if someone is waiting at the other side with a dangerous weapon like a shotgun. Best approach is try shooting through the door and hopefully eliminate an enemy, throwing a frag grenade inside of the room or using a Stun Grenade from ACT3 weapons. (CW Flash Bang won't work on NPCs)

Boom! You've just made and played your own mission!
I hope you liked this guide!
And remember, you get dirty, and the world stays clean, thats the mission.

Fun Fact: This guide was made on the same day as when the Clean House mission took place.
