thing is. i don’t really know the order of all the Ultimates either. I’m kind of just winging it and reading what people suggest. The only order I know is…
Ultimates Vol 1
Ultimates Vol 2 (each 12-13 issues)
Ultimates Vol 3 (5 issues)
Ultimatum (event 5 issues i think) (everybody dies and your life is fucked)
New Ultimates (which i’m reading now)
Ultimate Comics: the Ultimates (present story currently 13 issues)
those are the only things I’ve touched that aren’t Ultimate Spider-Man or Ultimate X-Men
You’re missing Ultimate Avengers but it’s not a necessary read (I only liked the first arc and Tony is hardly there since it centers more in the Avengers team than the Ultimates team).
Then there’s Ultimate Avengers vs New Ultimates which takes place at the same time as the Death of Spider-Man arc does.
Anyway both go after New Ultimates and before Ultimate Comics: The Ultimates
