From the announcement:
Mantic Games will be in attendance at Gen Con Indy this weekend, and will be showing off a rather exciting new miniature! It's not yet been seen anywhere outside the Mantic offices, and it's sure to cause a stir.
If you're heading to Gen Con, you've got a chance to win $75 in credit at www.manticgames.com, simply by taking a photo yourself with Mantic's webmaster Chris holding the Secret Mini and posting it on the Mantic Games Facebook page. Full details are available at the Mantic blog.
See you at Gen Con!
