For the PBs stuff just set up a second controller dummy player on the skyscraper stage. Initiate a stun, PP, PP, CB!, PB!
hitting them into the cliffhanger and retrying the stage to get both the throw and attack cliffhangers helps you out with that.
Doing the above for each of the 23 characters gives you the following character titles:
*Use a Character for the first time
*Perform a Character's Power Blow
*Combo a Character's Power Blow from a Critical Burst
*Perform a Character's Throw Cliffhanger
*Perform a Character's Attack Cliffhanger
Then you have each character's sparring/exercise mode. Completing that gives you a title:
*Complete a Character's Exercise Mode
That alone gives you 138 titles.
Completing Story I believe should put you around 100-120 I think. So on the conservative side we'll say 102
240 is your current total.
You then have a title for completing each difficulty of Arcade (Solo), Arcade (Tag), Time Attack (Solo), Time Attack (Tag), Survival
Plus an additional title for completing all the difficulties of each mode. I think there are 8 or 10 difficulties. Assuming 8 you have a total of 53 titles from that.
So you're at 293.
The last 7 you can get for using a 7 character 10x online or 50x on/offline.
You can also get a title for unlocking all of a character's outfits.

Or you can just play ranked matches as in v1.03 that now will unlock costumes and characters
