It's available on-line via the 2000AD website. Or via Forbidden Planet. And Amazon. And a zillion others.
It's been getting some pretty good reviews.
But if you live in the #Yeovil or South #Somerset area (or are just passing through), could I suggest that you snag a copy from Atomic Comics & Games of #Yeovil ? It's my local comic-book shop; it's a great little shop - one of the best in the UK - and the guys who run it have done an amazing job at creating a comic / gaming community there.
