Details for the Cowboy Approach

Use the radio to draw off three of the four mutants. Kill the remaining mutant behind you in under three turns, using snipers or the .223 pistol. Take the holodisc and radio from his body. Read the holodisc.

Gather your NPCs and enter the base. Kill all mutants on the first level.

Go to the computer in the east corner. Hack into it to disable the forcefields. Use the radio on the computer to set up remote control.

Go to the field computer, hack into it, and set the 'Pest' setting to 'Large Pests' so robots attack mutants.

On the last level, repair Mr. Handy and use the 'Science' skill on him to blow up the forcefield to the vats. Kill the mutants and COC techs.

In the footlocker next to the elevator on the last level, find and take two plastic explosives.

On the last level, confront the Super Mutant lieutenant (250 hit points) and his two guards, who have gatling lasers and rocket launchers. Use the .223 pistol or a strong weapon aimed at the eyes for about six hits to defeat the lieutenant. Alternatively, attack him directly, letting his guards' attacks damage him.

After defeating the lieutenant and guards, lockpick the locker next to the dead guards to take the key.

Go to the computer area (where Mr. Handy blew up the forcefield). Use the 'Science' skill on the Vats control computer and access it. Save your game. Access the computer again, find the desired code, and exit the base. Ensure all creatures are dead on Levels I, III, and IV.

Go to the third level and use the radio to toggle the forcefields. If the radio fails, use the plastic explosives. Escape the base.

For the final required mission, head towards the Cathedral, located two square units south of the Boneyards.
