This mutator was made to fix an inconsistency with the AVRiL, which, upon firing, only applies a knockback to the player when he’s playing offline. Loading this mutator will make the knockback apply to online play as well.
The mutator features an option to only apply a knockback when the play is mid-air, to prevent him from being knocked off of ledges.
Players can take advantage of the knockback and use it for trickjumping. Here is a small demonstration of the possibilities:[sc:youtube id=”8gW_tEZRaS0″]
The above video shows that this mutator can cause gameplay balance issues. I refer you to the release thread on Vehicle Masters for discussion on this subject.
