I started reading these with all hail megatron and I would like to go back the beginning of idw. Is there a list of their work?
I am presuming you mean their "Generation 1" titles, and not the Movie-Verse, Animated etc. So, their G1 continuity, in an approximate reading order: Megatron: Origins Infiltration Stormbringer Spotlight Vol 1 Escalation Spotlight Vol 2 Devastation Spotlight Vol 3 Revelations All Hail Megatron Vol 1 All Hail Megatron Vol 2 All Hail Megatron Vol 3 All Hail Megatron Vol 4 For All Mankind (Ongoing Vol 1) Bumblebee Ironhide International Incident (Ongoing Vol 2) Drift This very site contains details of the various story arcs etc. TFArchive - Transformers comics, cartoons, toys and everything else! - Transformers News & Site Updates is also a good place as it has an "IDW Map" and makes very clear what the different stories are, how they fit together, reading order etc.
Don't forget Maximum Dinobots after Revelations and Last stand of the Wreckers after All hail Megatron vol 4 (I guess). It's sacrilege to forget Last stand of the Wreckers (Max Dinos is also pretty sweet).
thanks guys i have all the spotlights and all of the ahm,s and the last stand of the wreckers and stormbringer oh and bumblebee's now i know what i need to finish off the set
Oops, that's what I get for doing it by memory at while at work. Of course, LSOTW and Max Dinos are probably two of the best!
