The Pitt bugs

Problems retrieving your gear

 * For some people, if, after the third fight in The Hole, you don't retrieve your gear, then complete all three quests, it is no longer in the footlocker. Verified (possibility)

Ashurs Speech

 * Do not talk to Midea during Ashurs Speech. He will stop talking and you'll probably walk around to try to talk to people. Once you have done so, You'll walk back to the spot where Ashur is having the Speech. Your game will begin to glitch and your X-Box may freeze up. So if this happens go to your last save point; Which would be when you left Midea's House.

Exploits

 * Confirmed that it works on the Xbox 360 GOTY edition, with all the content installed, and if you had Wernher conceal a gun on you, in theory it should work with the knife as well, any way, go through the dor after all your gear is stolen, drop your weapon and ammo, (Don't move any more than needed, if you see the raider interrogating the three slaves the door will lock behind you) turn around and head back through the door, than go through it again, drop your weapon and ammo, then repeat the process, do it as many times as you wish, be careful though, the game might freeze on you, not only do you get all the ammo and guns you dropped, but when you retrieve your stuff, you will find a bunch of 32 pistols and ammo in your locker.

Map marker glitches

 * Installing The Pitt causes User placed map markers to cease functioning correctly in a large area around Megaton, Merseti Train Yard, Agathas House, The Bethesda Ruins and Wheaton Armory i.e the map markers send the player in the opposite direction or halfway around the map when all the player wants to do is move a few feet (confirmed). Also when you go in to Megaton its self, even if you've previously 100% explored it the bottom 1/4 of the map will be blacked out and when you go by the Women's Washrooms the whole Megaton map reverts to "unexplored" status.

Terrain Glitches
It is a possibility that after downloading or re-downloading The Pitt that areas within the Steel Mill will de-solidify allowing the player to get outside the area of the map with ease, though when getting higher in the Steel Mill, it becomes impossible with the loss of footing higher up making certain ingots impossible to locate. This error does not correct itself nor does it change upon starting the game over or reloading a save. The only way to fix this problem is to replace your Pitt download.
