Seemed most-appropriate to post this directly after the Terrain Corner for the day. Mantic Games has posted some new free scenarios for The Walking Dead: All Out War. They're tied-in with the new TerrainCrate kits that are available to pre-order from their website. However, I'm sure you can still manage to play them if you've got some other terrain hanging out.
From the announcement:
To celebrate the impending TerrainCrate apocalypse, we're offering some brand-new scenarios for The Walking Dead: All Out War that use the Hospital, Quicki-Mart and Crystal Peaks Campsite TerrainCrate sets. You can download them for free here!
