"It Came From Outer Space" includes a full cast of Kefling-sized alien characters and an entirely new kingdom where, playing as their Xbox Avatar, players can build an entire alien city for their extra-planetary friends.

"Aliens have crash-landed in the Kefling world and you and the Keflings need to use your mad building skills to get them home," said Mike Nielsen, lead designer on the DLC. "You'll be building giant robots, crazy alien structures, and even robotic Keflings all in the name of repairing their mother ship. There's plenty of new stuff to explore - a new kingdom, new characters, new resources, new buildings... It's pretty substantial."
