If anyone missed out on this comic, a new kickstarter was launched to help fund a graphic novel set. You can get some pretty sweet swag. Unfortunately international shipping is pretty rough, but signed copies of the first 4 issues are available, as a collectible I think it’d outweigh the pricey shipping.
It’s a really good comic, the other issues were put out by Black Mask Studios. There’s some amazing other comics from them: 4 Kids Walk into a Bank, Godkiller, The Forevers.
