This teaser for Activision’s latest installment in their popular Call of Duty first-person shooter series takes us through humanity’s long and diverse history of masked warriors before culminating with the 21st century soldiers that populate the world of Call of Duty: Ghosts. Back in the capable hands of Infinity Ward (developer of the original Call of Duty and Modern Warfare series), loyal fans and newcomers to the series alike can look forward to a new story, setting and cast, and a completely rebuilt Call of Duty engine. Available for pre-order now at the series’ official website, Call of Duty: Ghosts will first see the light of day online on May 21 as part of the next-gen Xbox console reveal with the official launch due in Fall 2013. The game will be available for Xbox 360, PlayStation 3 and PC. Look forward to new details in the coming months and after the reveal.
