These mechanics aren't just new to Rivals 2, they're new to the entire platform fighter genre!
Check out Pummel Special, Ledge Special, and Getup Special from our Kickstarter trailer:
Special versions of these attacks have a ton of uses. Some are slower and stronger. Some create alternative stage control. These specials keep your opponent on their toes and give you another option during grabs, on ledge, or times you missed your tech.

Is Rivals 2 still designed around no mashing? Recall hearing that there was an RPS around pummel/special pummel instead of mashing out of grab, but could be wrong.
