Zombiesmith and Flytrap Factory are going steady with their Netherworld's Edge: Keystone Kickstarter campaign. They're over 3x funded with a little over 2 weeks left in the campaign. As such, they've added a new pair of starter sets to the mix, as well as a new pledge level.
You can add either of these to your pledge for just $25 each. Also, they've added the Rathound to the add-ons (it was always supposed to have been there, but rats are tricky and this one had escaped for a short while).
The new pledge level is for the gamer who wants it all... and then some. You get one of everything that's part of the campaign, plus a custom mini made just for you. There's only two of these pledge levels available. So you'd better hurry if you want to be the one to get it.
