Zen Studios has put out a sing-along trailer for its upcoming Angry Birds meets MOBA game, CastleStorm.
Interested participants just record themselves singing along to the melody and submit it to Zen at CastleStorm@zenstudios.com or through Twitter @Zen_Studios by November 16. Winners receive codes for the XBLA game, a code for the next Pinball FX2 table, and Zen Studios slippers.
If you've got the voice, comfy slippers are definitely worth the ensuing public humiliation.
