I like to post original content, but I'll admit sometimes it's just fun to share different finds with you folks.
The Shambling Un-Dead is a free level 0 tournament adventure for Dungeon Crawl Classics. Unlike typical O level funnels, players only control one character at a time. Death isn't the end though. When one character dies, another crawls out of the woodwork.
The adventurers are common folk trapped within a city overrun with undead. It's a classic scenario idea, but the adventure presents it in a fun and refreshing way. The encounters are really cool and sort of creepy. There are undead fiddlers, babies, and sailors.
Even if you don't play DCC, you should check the adventure out. I'm sure you'll find something useful or entertaining.
