Killing Floor: End of the Line, large-scale downloadable content for the sci-fi horror first-person shooter, is now out on Steam, developer Tripwire Interactive announced today.
The new update includes both free and downloadable content. Paid content includes a Neon Characters DLC pack featuring DJ Skully in "voltage blue" and Mr. Foster in "magma red," as well as a community neon weapons DLC pack featuring four new guns.
Free content includes two new Wave Mode maps by the name of "Siren's Belch" and Stronghold," and one new Objective and Wave Mode map called "Transit".
The original Killing Floor was released as an Unreal Tournament 2004 mod in 2005, while a full retail release followed in 2009. Players spent their time fighting off waves of strange creatures in London with the help of purchasable weapons and perks to determine bonuses for armor, movement and more.
