For those that are not scholars of Arc System Works fighting game series, BlazBlue, here is a quick primer of the order they belong in: BlazBlue: Calamity Trigger is first, followed by BlazBlue: Continuum Shift. BlazBlue: Continuum Shift picked up the story where Calamity Trigger ended and introduced eight new characters, seven of them were playable either out of the box or through DLC, leaving one character out in the cold.
Why is this important? Well, Arc System Works have officially announced that BlazBlue Continuum Shift Extend is coming to the Xbox 360. In addition to the standard balance fixes for all characters, BlazBlue: Continuum Shift Extend introduces the following new features:
New rules for online play, including 2 on 2, 3 on 3 and 2 on 4 battlesThe eighth character introduced in BlazBlue: Continuum Shift, Relius Clover, will also be playable. If you only played the first title, that name will ring a bell or two. Relius Clover is Carl Clover's dad, oh and he's also the one responsible for building the Murakumo units causing all the havoc.
Updated Abyss mode
Improved key recording in training mode
The high difficulty 10 stage Unlimited Mars mode from the arcade version
Inclusion of all the paid Continuum Shift download content
Four new scenarios for story mode
Inclusion of a refined version of BlazBlue Calamity Trigger's story mode, with all new voice acting
As of now, Arc System Works have not announced whether or not BlazBlue:Continuum Shift Extend will be another retail game or a DLC add-on. I would plan on this being another $40 retail release with more content being announced later at the Tokyo Game Show.
