Elsewhere in Prototype 2, you can upper-cut helicopters.

Entitled the embarrassingly lame "Butt Kicker", the power upgrade is actually a modified version of the game's explosive human javelin Bio-Bomb ability — allowing you to, ahem, kick foes in the butt really, really hard.

It sounds dumb as hell, but the trailer actually does a good job of the selling the upgrade. Well, sort of anyway. See for yourself after the break.
