It's been 15 years since a tiny team of modders first released Killing Floor, kickstarting the popular, blood-soaked horror franchise. Now, the game's veteran devs have dished on the upcoming Killing Floor 3, discussing just how much has changed at studio Tripwire Interactive in those 15 years.

In the developer-diary video, some of Tripwire's veteran devs reminisce on the history of the Killing Floor franchise, from its origins with a tiny team creating on a restrictive schedule and budget, to the increased size and scope of Killing Floor 2.

When it came to creating the third game in the franchise, the developers are looking to find the perfect balance between old and new. "I knew I wanted it to return to [Killing Floor 1's] level of horror, have some cult elements, but become a little more mainstream," said studio creative director Bryan Wynia, who only joined Tripwire after the release of Killing Floor 2, but has been a fan of the franchise for a lot longer.
