Fans of fighting games who have purchased Ultimate Marvel vs. Capcom 3 have an
extra reason to be joyful this holiday season, as one of the modes which was
highly touted during the months leading up to release will be patched in and
released as of today. The mode
that I am referring to is called Heroes and Heralds mode, and it looks to add a
much deeper single player experience (in both offline and online format) for those
who are looking for it.
Essentially, Heroes and Heralds will have you pick a side (Heroes or
Heralds), and fight enemies in different zones to gain control of those
locations. 
Here is Strider with the Herald Silver Sheen
As a brief aside, the faction that you choose will not limit
your ability to choose your favorite characters (for example, if you choose
heroes, you could still choose Dr. Doom for your team), but if you choose the
heralds side, all of your characters get a silver shine to them (akin to the
silver surfer, one of Galactus’s more esteemed heralds). Personally, I think that more fighting
games need systems like this, so that people who are looking to play the game,
but may not be amazing at the online component have something to justify a
purchase. We will all see how the reactions are once the free DLC (which
will be released by the time you read this) gets into the public's hands.
