Getting secret items
Did you know that there are some weapons and gear that you're not supposed to get? All of which can be obtained on the PC with a console command, but what about the people on the 360? Fear not, for I will tell you how to break the game and get Dad's Wasteland Outfit, Col. Autumn's Uniform, Col. Autumn's 10mm pitol, and Col. Autumn's Laser Pistol.
There are two ways to get Col. Autumn's suit. The first is right after your Dad dies. If you put your cursor on him while in first person and then hold left bumper and rotate the camera, you can loot his body while he's still inside of the chamber. You can take his unique outfit, Col. Autumn's Uniform, and his unique pistol, Col. Autumn's 10mm pistol, and you can also loot your Dad's unique outfit, Dad's Wasteland Outfit, in this way.
The other way happens during the quest, "Take it Back!" Get your reward from Sarah Lyons, but tell her that you need a few minutes, that won't start the final sequence of the game, so you can still do whatever you need to in the wasteland, including getting a certain outfit and weapon. From Rivet City, head to Jefferson's memorial. You'll see that it's surrounded by a barrier and impossible to get inside.
Or is it? Find the barrier facing Rivet City and go to the far right of it. Take all your clothing off (Not sure if this makes a difference, but it worked for me...) and start jumping at the rock pile to the right of the barrier under the stairs. It may take a few tries, but once you make it to the top, you can simply drop down inside of the barrier. Up on the walk are some FRIENDLY (Not sure why they're friendly...) Enclave soldiers you can talk to them if you wish, but the only diologue choice is, "See you later". Go inside of Jefferson's Memorial, and the troops in here WILL be hostile. Kill them and go to the main Project Purity room where Col. Autumn is. He won't attack you or approach you, so shoot him in the head. (NOTE: Best to shoot him from behind, or he might fall in the water, and all your efforts will be waste, unless you reload your save point) Now, loot his body! He'll have his cloths and ammo on him, but his weapon won't be in his inventory, so you'll have to pick his unique Laser Pistol off of the floor. This pistol is really cool (Fully Automatic!) and his suit is even cooler. To get out, just go outside and fast travel somewhere else. I don't believe this really effects the outcome of the game, as you can just Talk to Lyons once you get inside about who will be the one to make the sacrifice.
