What is The Pitt?
1.
The first version of the Pitt added to Xbox Live was corrupted, causing walls and characters to appear as question marks. Microsoft since removed it and a new file was uploaded, though there are still many bugs in the add-on, like crashes, audio not playing, and certain details that bleed through walls (you'll see it if you look at the right spot).
Overall I prefer the Pitt. It might not have a super awesome story like the main game, and it might have a few bugs, but the new stuff is well worth it. If you've got 800 points burning a hole in your Xbox wallet, then go buy the Pitt.
Dude: Hey, there's this guy talking about Trogs in the Pitt expansion. What's a Trog?
Other Dude: Heheheh
Dude: DUDE! Did that girl actually start stripping in the Pitt expansion?*
Other Dude: Wut? OMG IMMAGOBUYITNOW!
*There is no nudity or stripping girls in the Pitt, sorry.
