Hyperballistic, called It's also a Gun before being unlocked, is a passive ability only available to Ruby Rose in RWBY: Grimm Eclipse. It must be unlocked by reaching level 10 as Ruby. This ability reduces the number of sequential combo hits required to gain a bonus to ultimate from 24 to 16. It costs 2 points to use.
Hyperballistic is particularly useful later in the game, when the number of enemies can make it difficult to build up large combos.
Early Access Edit
In Early Access, Hyperballistic reduced the combo to gain a special point from 12 to 8, and was unlocked by reaching level 10 as Ruby as least once.
