Pirates, Vikings and Knights II

Pirates, Vikings and Knights II is a multiplayer team-based first-person action video game, developed as a total conversion modification on Valve proprietary Source engine. The game was released in beta development stages, with its first public release on 1 January 2007. The first full version of the game was released on 8 August 2025.

The game is a sequel to Pirates, Vikings and Knights, a modification for Valve's earlier GoldSrc engine created by three UC Berkeley students (Garrett Moore, Matt Bishop, and Kris Hauser). The game is set around three teams, the pirates, the Vikings and the knights—each with four distinct classes and abilities—battling in a variety of game modes across various Medieval, Norse and Caribbean environments.

The game has been received positively by the industry's critics, being praised for its originality and graphical quality. By the end of February 2008, the game had acquired over 6.5 million player minutes per month on Steam.
