The GeForce Website announces that open beta testing is now underway for Warframe, Digital Extremes' free-to-play multiplayer shooter. They offer a new Warframe PhysX Trailer showing how the game favors their hardware, and explain how the open beta works, since it's not yet announced on the Warframe website.

Today, Warframe enters into open beta, which is generally regarded by gamers as a free-to-play game’s official launch as all can play without invitation or the need for a beta key. “If you want to be a super-powered space ninja,” says Dave, “you should join. If you like frantic third-person action, you should join. If you like to see sci-fi take a unique visual direction, if you like guns, or if you like swords, you should join.”

If you do join you’ll discover a highly entertaining co-op shooter with advanced graphics, topped off with a variety of hardware-accelerated PhysX effects, like those shown in our video below, which add to the sci-fi spectacle.
