Minor ACPlus XBox 360 Impressions
(This is info I gathered from various sources)
--Unlockables appear to have remained intact (therefore you can unlock most everything via Mission Mode / Survival).
--Online Play is barebones:
---No lobbies can be set up, but you can mark for yourself what match settings you want beforehand (i.e. ban Justice/Kliff/Golds/Blacks/EXs)
---No 3-on-3 play online, unfortunately (offline only).
---Online seems to be based on line stability, therefore it's best to connect with players closer to you. (Wi-Fi notwithstanding). So long as the connection is stable distance may not matter so long as it isn't outside of the continent you're on. It's probably not as stable as BlazBlue's netcode, but it should suffice at least until ACPlusR patch arrives.
--Still no Movelist in-game translations (my personal pet-peeve! >_< ), though I can provide that as needed.
--Progressive Mode seems to have been removed, most likely because the native display has already been set to as high a definition as it can go.
--If you need help with Survival Mode, I wrote a FAQ on my other site, good luck getting the Ultimate Double-Edged Hell Trophy!
One thing I want people to be aware of is that EX Mode characters have features that the current changes to ACPlusR are BASED off of, so don't write them off as bad so quickly without trying them out for yourself. The last EX Mode revision was in #Reload, so I think ARC System Works would appreciate it if someone played them at least a little, even if they are bannable currently. At the very least it's good prep for learning ACPlusR.
Bear in mind this is just info I gathered, I do NOT own Accent Core Plus for X-Box 360.
