Indie zombie survival game based on Unreal engine 2.5. Wondering whether to buy? Fret not -
Killing Floor will be free to play for a week beginning July 4. New weapons and skins are also packaged in the update as unlockables or DLC, shown below.
Community Steampunk Weapon Pack
The Orca Bomb Propeller – The Orca Bomb Propeller tosses little delayed explosive bombs. Good for those bank shots!
Multichamber ZED Thrower – A steam-powered lead launching auto shotgun, with a secondary steam discharge that will knock enemies away!
Single Piston Longmusket – A finely crafted long rifle from the Victorian era fitted with telescopic aiming optics.
Dr. T’s Lead Delivery System – Thy weapon is before you. May it’s drum beat a sound of terrible fear into your enemies.
Golden Gun Weapon Pack 2
Golden Tiger-Striped Hand Cannons
Golden Chainsaw
Golden Flamethrower
Golden AA12
So you'll have 7 days to demo it out and work out whether it's worth the purchase. At $4 for the base game it's probably a no brainer — though you may wish to consider owning all the DLC's ($12.50 for whole shebang).
The crew and I play this together every few weeks! Absolutely great game! Even better with friends!
