The Brass Knuckles is a hand-to-hand weapon used by Deke in the Fear Effect series.
Although Deke prefers to attack his enemies directly, he does at times enjoy sneaking up on a foe. The Brass Knuckles are crafted with a metal spike on each knuckle and allow Deke to deliver maximum pain to anyone unfortunate enough to be on the receiving end of his punch.
The Brass Knuckles are a close-range weapon and should be used in situations when you can sneak up on an opponent. When the targeting cursor turns red, Deke can kill an enemy with a single strike from the Brass Knuckles.
