I didn't see anything about this already posted, so I hope this isn't old news. When I went online this morning, darned if there wasn't a downloadable quest available. "Letter from Lionel;" accessible from the introductory menu by selecting 'downloads'.

Isn't there already an offline quest with a similar name/theme? Perhaps it's a variation, or perhaps my memory's just wierd. Haven't had the opportunity to actually play it yet, but will soon.
