Without going into spoilers, can I get confirmation that the choices made in previous episodes of The Walking Dead affect gameply/story in the DLC "400 days"?
The FAQ on telltale says that it does:
Yes. 400 Days will check to see if you have a Season 1 save file. The decisions you made in Season 1 will have an effect on your 400 Days experience. And yes…choices made in 400 Days will resonate in Season 2.
For some reason though, I didn't see ANYTHING related my prior experience/choices... and I confirmed that my save file was intact (XBOX 360).
