Bridge tower

The  of Rivet City is home to Rivet City Security and contains the sleeping quarters for the guards as well as a well-stocked armory.

Armory
The key to the armory is carried both by Harkness and Lana Danvers. A Mr. Gutsy named Private Jones guards the door but he can be easily distracted with a successful Speech check. Be aware that there is a hostile Automated Turret inside, using a Stealth Boy is recommended if you do not want to turn the whole town hostile. You can also use the Chinese Stealth Armor to access the items, just make sure you keep some distance between yourself and the Automated Turret.

Harkness opens the armory door from time to time, but upon attempting to enter Jones and Harkness both attack you and lock the armory door.
 * A possible way to get into the armory without hostility IS possible. While this editor was playing, I told my companion (It was Sergent RL-3 at the time) to wait just outside the armory door. Then I waited for Harkness to open the door and my companion automatically killed the hostile turret. And because my companion killed it, no one was hostile, then inside where two rive city securities who were fleeing, I could walk right in and loot. Also note that some of the items in the armory are green and can be taken freely, such as the Rock-It Launcher schematics.
 * (100 LP required) Another way to get in without getting hostility is to post your companion outside the door, use a stealth boy, pick the lock and loot before your stealth boy runs out. There is a slight karma loss involved but you can easily get it back with purified waters in the time it would take to just sit outside the door and wait for harkness.

Notable Loot

 * Schematics - Rock-It Launcher
 * Scoped .44 Magnum
 * various suits of Combat Armor, weapons and ammunition.
