A free weekend is now underway on Steam for Call of Duty: Ghosts for those interested in sampling the first-person shooter sequel. The game is also carrying a 50% discount through the event, allowing those who enjoy playing to get it on the cheap. Here's the pitch:

Call of Duty®: Ghosts is an extraordinary step forward for one of the largest entertainment franchises of all-time. This new chapter in the Call of Duty® franchise features a new dynamic where players are on the side of a crippled nation fighting not for freedom, or liberty, but simply to survive.

Fueling this all new Call of Duty experience, the franchise's new next-gen engine delivers stunning levels of immersion and performance, all while maintaining the speed and fluidity of 60 frames-per-second across all platforms.
