A tradepaperback collection that reprints two separate (but continuity connected) crossovers. It includes: X-Men And Alpha Flight #1 & #2, The New Mutants Special Edition & Uncanny X-Men Annual #9.
It was this trade paperback that gave the name 'Asgardian Wars' to the two cross-overs that were previously published.
