Et Tumor, Brute?

Et Tumor, Brute? is a quest in Fallout: New Vegas which involves removing Caesar's Brain Tumor.

Quick Summary
Caesar needs you to get the supplies to cure his headaches and remove his brain tumor. You will need to find a functional Diagnostic Scanning Module or buy a set of surgical tools (999 caps at the New Vegas Medical Clinic) and a Doctor's Bag to operate Ceaser manually (medicine skill level 75 is needed).

Detailed Summary
If you choose to find the Diagnostic Scanning Module, you must make your way towards the radiation and ghoul ridden Vault 34 (similar to Fallout 3's Vault 87). You can find the vault north of the NCR's Camp Golf or west of the NCR's Sharecropper Farms near New Vegas. It is recommended that you bring several Rad Away and RadX. You will notice the radiation right off the bat as the entrance is brimming with radiation. Due to the intense radiation, there will be several geckos on the way in and once entering the vault you'll find approximately 20-30 ghouls of various types inside. Once inside your objective will be to get to the armory, however the door is locked and must be accessed by using the terminal in the Overseer's Office. To get into the Overseer's office, two terminal passwords must be found in the Vault. The security terminal password is in the first flooded area, on a dead Glowing One/vault technician under a desk, and the utility terminal password is through the clinic and into the next flooded area, on the right, on another vault technician. After finding the passwords, go to the door just before the entrance to the armory (this is the Utility Room), and activate the pump system on the terminal. Next, in the once-flooded area where you found the utility password(Which now is behind a closed door -labeled Security Station A- which you must go through), use the security terminal to unlock the door to the Overseer's quarters.Finally, go to the Overseer's office where there will be two Vault-Tec Turrets protyecting the ghoulish Overseer, obtain the password from his body and use his terminal in order to unlock the armory. Alternatively, finding the terminal passwords can be avoided altogether, but requires a Science skill of 100. Now make your way to the Armory which is located through the medical clinic and inside is guarded by two ghoul-like security guards.

Notable Loot
semi-automatic rifles, automatic rifles, sniper rifles, a block of C4, a mini gun, a rocket launcher, energy weapons, and grenade launchers. Most of this can be obtained in the Overseer's quarters. Accessing the Overseer's rooms requires 2 pass codes that you can get from 2 dead scientists, now Ghoulified, that can be found submerged inside the Vault.

Bugs

 * It is possible for the second Vault Technicians password to be replaced by five bottle caps, if so simply reload and the problem will dissapear.
