Players Handbook; SRD Link

Great Cleave(Fighter)

You can strike a number of adjacent foes with a single mighty swing.

Prerequisites: Str 13, Cleave, Power Attack, base attack bonus +4.

Benefit: As a full-round action, make a single melee attack against a foe within reach. If you hit, you deal damage normally and can make an additional attack (at the same bonus) against a foe that is adjacent to the previous foe and within reach. If you hit, you can continue to make attacks against foes adjacent to the previous foe, so long as they are within your reach and you threaten. You cannot attack an individual foe more than once in a round with this feat.
