The really good thing is that you can read their WotW online
stories have been collected into one volume which I highly recommend - it is a little thin but 2000AD writers have to pack a lot in (as they only get 5 pages a week) and the production values are the highest setting the stunning art off. Stickleback
hasn't yet been collected but will be well worth it when it is - this week giant steam-powered robots have burst into the demonic Wild West Show and the "heroes" have escaped into the stomach of the World's Fattest Man where things have just got really weird!!
Unlikely to be collected anytime soon but they also worked together on a Judge Dredd
story in which a Victorian time traveller, Herbert George Sewell
, turns up to cause Judge Dredd no end of temporal bother. He appeared three times in the end and the last one seems to have concluded things (although there is always the potential for him to return) with the last instalment involving him and his time-scattered selves on a time-travelling bicycle.
They have both also worked on Kingdom of the Wicked
which everyone who has read it speaks highly of (I keep forgetting to pick up a copy) - although it isn't actually Steampunk.
