Job ads give us the first details about Sledgehammer Games' 'action-adventure' Call of Duty spin off

We called it back in December: Sledgehammer Games are gearing up for a new Call of Duty title, we said, and with Activision's recent press release the news has been confirmed.

But what do we know about the game? Activision has described it as an 'action-adventure', and according to a report by G4, it probably won't appear before 2012.

Sledgehammer was previously looking for a sound designer, lighting artist, lead online/multiplayer designer, lead environment artist and gameplay engineer to work on it's Call of Duty title - the studio recently started advertising for a senior character artist, lead online/multiplayer designer, gameplay systems engineer, development  audio software engineer, temporary concept artist and associate producer.

"The candidate will be involved in the creation of gameplay related features for an unannounced high-end console title, bringing areas such as the camera system and character development to a new level," reads the gameplay systems engineer posting. 'Camera system' certainly suggests that a view other than the series' first-person standard could be on the cards. MW2 flirted with third-person mode as a multiplayer option.

Meanwhile the posts for concept artist and audio engineer both mention vehicles - a responsibility for the latter reads: "Develops and enhances audio systems that work in conjunction with AI, physics, vehicle, and animation systems."

With Battlefield: Bad Company 2 about to 'wow' multiplayer crowds, could Call of Duty be about to follow suit with regards to vehicles? Let us know what you think - and what you'd like to see in a radically new Call of Duty...
