Good to see a place that collects all the stuff from the event, thanks!
Totally missed the AoT and Aquaplus collabs.
I'm mostly looking forward to how Mai's moves work out in this collab (and the other guest costumes). Her model is nice, surely, but it's also really plain. Kasumi's outfit already looked like something Mai would wear, and Mai's version has no real defining features in this universe. Hopefully they saved all that for making her moveset distinct.
I really love how much life DOA5 has gotten out of this release. Never would have expected these kind of guest or collabs all the way back when buying the original version on 360. Now I only wish a lot of this stuff would be forward compatible with the eventual DOA6. KT isn't bad at keeping their stuff in the ecosystem for the Musou series, so hopefully they do some of that with the DOA series in the future.
