Tripwire Interactive has updated its EULA for Killing Floor 2 stating that any mods players create for the game must be distributed free-of-charge.
The end user agreement update, via PCgamesN, went live a couple of days after Valve announced it would allow mod creators to start charging for their creations. Bethesda is the first company to endorse the new incentive, and if we're interpreting Tripwire correctly, it doesn't sound as though it will follow suit any time soon.
"Your Mods must be distributed for free, period," reads the clause. "Neither you, nor any other person or party, may sell them to anyone, commercially exploit them in any way, or charge anyone for receiving or using them without prior written consent from Tripwire Interactive.
"You may exchange them at no charge among other end users and distribute them to others over the Internet, on magazine cover disks, or otherwise for free."
This is the second time the developer has updated its EULA, the first pertaining to its stance on abusing other players or using cheats. If a player is found guilty of either, Tripwire said it would revoked the offender's CD key and ban them from the game servers.
The ability for mod creators to charge for their creations has supporters, such as Garry's Mod creator Garry Newman, but also detractors. A Change.org petition asking Valve to remove paid content from Steam Workshop has received 90,377 signatures of 150,000 needed as of press time.
Killing Floor 2 is now available through Steam Early Access and will be made available on PlayStation 4 later this year.
