If you’re looking for information on the 2011 Halloween badges, please see this post.
Foursquare has launched two new badges to celebrate Halloween this weekend: Halloween 2010 and Spooky Swarm.
Halloween 2010 is easy to unlock, just include “Halloween” in your shout when you check in. The unlock text reads:
Happy Halloween from foursquare! Here’s to hoping you came up with a better costume than The Jersey Shore.
Spooky Swarm is a little tougher. We’re not clear exactly which swarming venues will unlock this badge. We’ll update this post as we learn more. UPDATE: Spooky Swarm is only for swarms that happen at night, presumably through October 31. The unlock text reads:
You have forged a community to protect yourself from the dark ghouls trolling the overworld to steal your soul. Arm yourself with this badge as an amulet to ward off these wretched demons. Or just trade it for some Skittles!
