So far, it looks like there are 2 options. A VIP edition for $75 (which includes a Cartridge, Manual, Box, Sharknado DVD, Tara Reid Autograph, as well as more goodies to be announced later) and a Standard edition for $35 (which includes a Cartridge and Manual)
Additionally, Scott is looking for Sharknado inspired art that will be incorporated into the manual and/or art cards. These can be drawings, paint, photoshop, or whatever you feel most comfortable doing it in. Participants will be acknowledged in the manual. The Winner will receive a Sharknado Prototype Cartridge
