Peoria ( mission ) Peoria is the fourth or fifth mission in " " . Walkthrough . It is suggested you have at least 2 characters to accomplish all the objectives unless you have managed to hoard copious quantities of After Burner gum as there are 12 functioning turrets in the mission ( 13 in total ) . It takes 4 After Burner gum to overdose and destroy a turret ( Buffout , Mutie and Psycho are good , too . If you don ' t have any of those , you can use Mentats . But you need about 7 to 9 boxes of Mentats ) . Every turret has from 60 to 63 microfusion cells in them . It is good to take some extra characters with big Strength so you can carry all the cells home . Outside the village walls to the northwest , two dead raiders can be looted for a P220 and a few other worthwhile items , including a Scout Handbook . There are also two dead raiders northeast of the village up on the cliffs . One more dead raider and a dead tribal can be found on the cliffs to the southeast . There are three turrets around the top of the stairs into the store room ; depending on your decisions later in the mission , these will later fire upon the villagers unless you have sufficient After Burner gum to destroy them before you enter the bunker ( each turret requires approximately four applications ) . First battery . Now proceed down into the bunker from the staircase at the northern edge of the village . Follow the rooms on the left side to obtain the yellow pass key . Now backtrack and continue clearing rooms until you get to room with several lockers and a safe , use the keycard to enter the room and the first fusion battery will be in the blue locker . Now proceed to the right side of the bunker where there will be a power switch . Using this will activate the interior defense systems . These defense systems are automated laser turret s that will repeatedly switch between hiding under the floor and firing position . Listening carefully you can gauge when they are above or below ground and get past them without having to fight them . Second battery . The next area has far more radscorpions and large radroaches , as well as a few more turrets . There are two things you need to find here . The second battery , which is near the left side in a lone blue locker on a long walkway . The second thing is a power switch , near what looks like two electrical generators and is guarded by another turret . Once the power is back on you can proceed to the third and final area . The entrance is in the top left . Third battery . At the beginning of this area is another switch . Using this switch will cause the defense system to switch from internal to external . This gives you three options . Once through the area with the turrets there will be a few more roaches and radscorpions to deal with before you get to the final large room . Inside is the last blue locker with the third and final battery . Also in this room is four large radroaches and Roachor , a formidable opponent , despite being a cockroach . The room is also radioactive so taking Rad - X pills before entering is recommended . Once finished head back through the bunker . On your way back out , if you used the switch to change defenses to external , switch it back to internal . Dodging the turrets inside the bunker is much easier than getting through the turrets above ground .
