The first "Hillbilly Horror" Halloween event for Killing Floor sees not just the launch of a new theme* but also a new premium character skin, and 8 new weapons both in and outside of a the first ever weapons pack DLC. All previous DLC being either free or purely cosmetic. The whole "Hillbilly Zombies" thing reminds me of
Evil Dead: Hail to the King, but this is an infinitely better game. I enjoy the fact that this is the first time the game has been set in the US, and that the first explicitly American player character is a Terminator Chicken.
KillingFloor HillbillyHorror Halloween 2012Together with the new weapon pack (which is 50% off for the event) it's $10 until November 6th, you really can't lose.
*Previous Halloween events had an abandoned Asylum Rave setting.
