A new episode in Telltale's The Walking Dead series, dubbed "400 Days," will be available on Xbox Live Arcade, PSN, PC, Mac and iOS this week for $5. IGN says to expect it on PSN in North America this Tuesday, on Steam and the Telltale store on Wednesday, iOS on Thursday and in the Xbox Live Marketplace worldwide on Friday.

400 Days contains five different story threads, connected in some way through a crucial truck stop. Decisions from the Walking Dead's first season will carry over into the DLC, Telltale has confirmed.
