Activision and Sledgehammer Games have released a new trailer today that describes how the developer is telling a story in Call of Duty: Advanced Warfare.

According to creative director Bret Robbins, the developer is trying hard to achieve realism in a story about future war. For three years, Robbins says, Sledgehammer has worked on making the most interesting and believable story possible. The studio has hired military veterans from several branches of the special forces to share their experiences and help shape the narrative. Robbins says that these vets "bring a level of authenticity to the story."

Sledehammer has also worked closely with futurists, people who specialize in predicting and planning for the future. These people work on world, weapon, and uniform designs to make them as plausible as possible Sledgehammer wants the story to feel real, even though it takes place decades from now.

Finally, full performance capture is being used to more accurately portray characters' faces, movements, and emotions. Sledgehammer hopes that this will bring a greater level of character development and plausibility than in any other Call of Duty title.

Recently Microsoft announced that Advanced Warfare DLC will come to Xbox first. GameSpot was also able to go hands-on with Advanced Warfare at E3, and you can read our preview here.
