Sergeant RL-3

Sergeant RL-3 is a Mr. Gutsy robot, and a possible follower for the player character in Fallout 3. He can be purchased off of Tinker Joe outside the RobCo Factory for 1000 caps. However, the player character can only buy RL-3 if his karma is neutral. Otherwise Tinker Joe will just say Sergeant RL-3 "doesn't like the looks of you."

Sergeant RL-3 has an experimental soldier personality and is feared that he could be "unstable." When following the player he will often randomly say "Scanning area for targets." During combat he will also say things like "Another glorious day in the US army! Hooah!" making him quite a comical follower.

RL-3 can be used to hold items. In fact, his "storage compartment" has the best storage capacity out of all other available followers. (For example other followers could only hold 2 sets of power armor and a few weapons while Sergeant RL-3 can hold 3 sets of power armors and weapons.) Unfortunately, he cannot armor.

Combat
RL-3 uses a Flamer and a plasma weapon similar to a Plasma Rifle. He is extreme vulnerability to Energy Weapons, Minigun, Missile Launcher, and strong melee like those from Yao Guai and Deathclaw. He heals to full after combat.

It is not possible to repair him using repair skill. (Science might do it.) It is possible to heal him by sleeping.
