Colonel Autumn's uniform

Col. Autumn's Uniform is worn by Colonel Autumn.

Obtaining
Method 1) There actually is a way of getting this outfit before the end of the game in the PC version. During the Waters of Life quest after Colonel Autumn supposedly "dies", you can grab his belongings as long as he falls near the door. You must face directly towards the body with the cursor directly on the body in first person view. Once this is done, hold down the button that changes the perspective and you should be able to rotate the camera. Rotate the camera half-way and you should see a "Search Colonel Autumn" message. Voila! You can also search Dad and possibly everyone in the room if they fall close enough to the wall.
 * Colonel Autumn does not have his Laser Pistol during this part of the game. [edit: (360)other platforms unconfirmed. you can obtain Col. Autumn's unique pistol at this point, although when you see him later on he will have recovered both his unique armor and pistol.]

(Method 2) If you have missed your chance in the above method you still have another. After you have finished the American Dream Quest (the one at Raven Rock) and BEFORE you activate the robot Liberty Prime (aka the very last mission) fast travel to Rivet City. Once here travel West to the Jefferson Memorial and you should see the blue energy shields. Since you should be coming from the West side go up to where the energy shield cuts off and where the generator is, make a save here. The reason for the save is that when you are jumping over these rocks it is possible to get permanently stuck, any who continue jumping and you should make it over the rocks. The hole in the rocks is under the "stairs", not between the stairs and energy shield generator. Once that is over make your way inside the Gift Shop and into the Rotunda (there will be Enclave Soldiers in the gift shop). Col. Autumn will be standing in there like he is on the final mission but he will not talk with you. You now need to reverse pickpocket a suit of armor onto him that is in good condition (I used Enclave armor). After that leave the room and then re enter, Col. Autumn should be wearing the suit of armor you just put onto him allowing you to pickpocket his outfit.

Note:(Method 2) this may have been a glitch but i tried this after the patch that came with Operation Anchorage. When i got inside the two enclave Tesla soldiers were there but in the rotunda Col. Autumn was nowhere to be found

Note: Probably unrepairable by other clothes. So we'll never fix it up to 100% again. Also I don't know if it's only the xbox 360 version, but when you go into the Rotunda there will be someone marked there on the map but no-one will be standing there. [Edit: This glitch does work on the Xbox 360 version. However, reverse-pickpocketing does not seem to work so you are forced to kill Autumn instead.

[Edit : You DO NOT have to kill Autumn to get his uniform, to get his uniform get some Tesla Armor and repair it to the best of your abilities (I was at Level 13 when I did this) also grab a Stealth Boy, use the above Method 2 to get into the Rotunda to find Autumn standing the bottom of the metal stairs. Now use the stealth boy and creep up on him making sure you remain hidden, reverse pickpocket the Tesla armor onto him and leave the Rotunda, now go back in and Autumn should be wearing the Tesla armor and if you pickpocket him again you should be able to take his outfit, Congrats!

Note: When I did this, I killed him to see what happened after I got his uniform. It gave the quest info to "Clear the room", however the Enclave that are in the room when you follow through the quest normally, did NOT appear. So, I had to reload. I don't think this happens everytime, and it happened to me on the Xbox 360 then again on PS3, though.

Method 3) [For Xbox 360] after the lethal gas inside the Chamber kills Col. Autumn, your father, and the guards inside, grab the barrels that are around the opposite side of the entire Rotunda. Set them up just outside the Locked gate where the Colonel and Dad die, so that you are able to climb them to get on top of the Rotunda. You must now sacrifice one of your Mini-nukes (hopefully you have a Fatman) to fire towards the Statue in the Middle. the walls around the Statue are non clippable, so the mini-nuke will fly through harmlessly. With proper aim and maybe a few Reloads (heavily suggested you save once on top of the Rotunda) you can blast the bodies inside closer to the Door, of which you can use a technique similar to Method 1. If the bodies are close enough, you can merely face the door at an angle with bodies against it and it should allow you to search them. If they are further away, you may have to crouch, enter 3rd person, and face various angles (most of which do not face the door).

Note: DO NOT walk through the nonclippable wall! You will fall into the area, with water at the bottom, with no way to escape. A Reload is the only cure

Note: The area just above the computer your Dad uses that explodes is what gives off the radiation. If standing in the proper place, you can accumulate 50+ rads/sec.

Sub-note: it IS possible to search the scientist and guards as well, but you should be content enough with searching Dad and Col. Autumn, since the others inside carry common armour/weapons.

Method 4) After much trial and error I have come up with a simple and easy way to obtain Colonel Autumn's outfit and 10mm pistol that should work with every version I believe. This is done during the Waters of Life quest after the Lone Wanderer's Father has caused an overload of the Jefferson Memorials systems and everyone inside has collapsed.  Now you walk up to the airlock door and switch to the third person view which shifts the camera slightly over the right.  Hold down the button that changes view(L2 on the PS3 version which I use) and push the left analog stick forward slightly so that the camera is hovering just behind your right shoulder.  This makes the process a lot easier.  People on the XBOX360 and PC can quickly figure out the equivalent actions to take.

Now get right up against the airlock door with it on your right side and crouch down. Right away you should realize the "search dad's corpse" option, you can take Dad's Wasteland Outfit as a memento of your time together if you haven't gotten it already by some other means. But of course the real prize is Colonel Autumns gear but as you realize dad's bodies'(only his body can be searched) what I call "sphere of influence" is in the way. So while continuing to hug the airlock door "grab" his body and move forward, pulling it off to the side. Now move back to where Colonel Autumns body is and you should be able to just about reach his motionless corpse.

Note: I have only confirmed this on the PS3 version but I don't see why it wouldn't work on all versions.

Apperance
Fallout 3 only
 * The physical apperance however is pre-war (much like General Chase's uniform though it does have a differnt colour.
