Killing Floor 2 is coming to the PlayStation 4 because games are much more expensive to make these days and Sony has opened up the platform to independent developers, Tripwire Interactive has said.

"We love the PC as a platform and have been championing it for years, even in the dark days of 2005 when all the press could talk about was how the 'PC was dead.'" President of Tripwire Interactive John Gibson said in a post to the company's forums. "We've been very successful on PC selling million of games, and we've no intention of leaving the PC or relegating the PC to a 'second class citizen.'"

Gibson gives three main reasons for why Killing Floor 2 will be the company's first game to release on a console. The first reason, he said, is that the current generation consoles are more powerful, and have an architecture much more similar to a PC, a sentiment we've heard from other developers as well.

Secondly, Gibson said that Tripwire decided to work with Sony because it allowed it to remain "fiercely independent," whereas previously other console manufacturers wouldn't work with Tripwire unless it went through bigger publisher.

Finally, Gibson said that games are just much more expensive to make now. "When we made [Red Orchestra] we had 4 employees, [Killing Floor] we had 11 employees, [Red Orchestra 2] started with 7 employees and got up to 25 by the time it shipped," Gibson said. "[Killing Floor 2] is being developed by 50 people. With game development costs rising it is very important as a business to make your games available in as many places as possible, to as many potential customers as possible."

Killing Floor 2 is slated for release on PC and PlayStation 4 in 2015. For more on the game, check out GameSpot's previous coverage.
