New Boss Event: Bonecrusher

The last named infected of the season is also the largest. Bonecrusher wades in swinging a length of steel rail, shrugs off body shots and has to be broken at the joints. Strip its three armour plates, survive the smaller infected it throws at you between phases, and finish it before it reaches your position. Every clear earns Bonecrusher marks - trade them for the Crusher gun skin, a boss-kill emblem and a permanent title. Live October 3 to 9.
