Hey guys if you're interested in Zombicide, it's a great game. Peter and I saw it being demoed at Adepticon. They have a project on Kickstarter, which they are using to raise money to produce the game. They needed $20,000 but it's really taken off and they have raised over $300,000.
On Kickstarter you make a pledge towards getting the project off the ground and there are lots of break points. Depending on which pledge you make, you get different rewards. Peter and I have pledged $140 so far which gets us a copy of the game, with extra models and these special characters you have mentioned, plus a LOT more! (see list below)
Update: This is what you get at an Abomination ($100) level pledge!
Base game - 71 miniatures etc
3 Promo Survivors and their Zombie counterparts: 6 miniatures
4 additional Fatties - 4 miniatures
6 additional Runners - 6 miniatures
20 additional Walkers - 20 miniatures
1 additional Abomination - 1 miniature
6 custom black dice
6 glow in the dark dice
1 T-shirt
Total 108 miniatures!
If you love Zombies, then go have a look. The extra models are exclusive and look great. They have a Bruce Willis for example.
