Ubisoft have just confirmed another Call Of Juarez (the cowboy FPS series from Techland) game, this time called The Cartel. Here's what they say about it: "Call of Juarez The Cartel is set in present-day and brings the best elements of the Wild West to a new and modern setting. As a first person shooter with an immersive and mature story, players can expect to embark on a journey like no other – one that will take them from the heart of modern day Los Angeles, California to Juarez, Mexico."
It will also have a "gritty and relevant plot", and it will be out this summer. I also hear Ubi preview events a-callin', so proper details shouldn't be too far away.
