Im still a little skeptical if babalities will be in the game, and Im actually leaning towards brutalities intsead, since they were in the audio leak (along with the character intros) that was months back.
Seing the rest of the game so far, It would be awesome to have brutalities included.
Spoiler:
The achievement list also stated this:
Complet-ality (10 points)
Perform 1 of each type of "-ality"
It states "Each" type, not both types. Could mean that there are more than just 2 types.
