I tried it out once in Flood mode, and the first time I used it it killed the guy when I collided with him so I thought it would be just as good in other modes. But it seems to be a waste so far. I can't find a good use for it (other then flood mode). --- I want to move to a nice, quaint house in the suburbs with the T-Mobile girl and make lots of babies with her.
One use for it that I practice all the time: In rifle duels that you may lose or will lose, thrust around the corner/rock next to you and live. Or jump back out and surprise them with the final headshot. I've done this numerous times. --- GT: Whiplash941
I have had it used against me a few times and the enemies avoided otherwise certain death. I think it can be good but it seems really hard to use. --- "Actually, there was this one time...I grabbed the wrong whammy bar and deployed star power a bit too early. I stained the rug with my x8 multiplier."
