Step 1: Give Sulik and Cassidy large guns, set to "stay here" in combat.
Step 2: Tell them to wait at end of Military Base Corridor.
Step 3: Snipe 1st Supermutant, and let the rest get shot down in a 3-way crossfire while they get in range.
Step 4: Loot bodies, plant stuff onto Sulik to carry.
I forgot Step 3a: Tell Sulik to join you, dumbass.
Sulik turns hostile, I have to reload from start of military base.
As for AI hosing my plans, how about:
Planned to eliminate Mordinos using a Bozar (with Weapons Redone, so it's the ultimate sniper gun) and Cassidy with a Gaussrifle.
Stood down the street leading to the Desperado, at night so we could see them in the brightly lit casino, but they were out of range or shooting into the darkness.
Killed the first walking wall of a doorman with a Bozar crit in the eyes.
Second Doorman aims at me, hits the hooker and pimp nearby by mistake.
The Desperado is subsequently assaulted by a dozen shouting, knife-wielding tarts.
Bang goes my "sniper rifles mean only the mobsters get shot" good-character plan.
Or the classic "you encounter a caravan fending off robbers"
Always goes like this:
Merchant rushes in screaming, waving his stick.
1st guard fires his minigun, slicing the merchant in half.
2nd guard fires, killing first guard.
3rd and 4th guards hit the raiders, each other, and nearby trees a couple of times, run out of ammunition and possibly finish them off with their fists due to having better armor.
Guards 2,3,4 hand in their notices to the corpse of their boss, then tour the wasteland as a 3 Stooges tribute act.
The Chosen One and his companions finish rolling on the floor guffawing and cart away a trunkload of guns.
On a later-game version of that, since both sides were wearing the same assortment of armor, I accidentally shot the merchants guard while trying to "help". Since that would mean whovever survived would be hostile anyway, resorted to Plan B: Open up with the LSW and Deny Everything.
