Activision has officially announced Call of Duty, a new first person shooter series. The brand will feature "the 20th century's most monumental conflicts", and the first game will be set during World War 2. As mentioned last week, Infinity Ward (a company that includes developers who worked on Medal of Honor: Allied Assault) is developing this first game. Here's what we can expect from the game

Players assume the role of different characters from multiple sides of the Allied forces and experience the bonding and brutality of war as they fight along side their squad mates through a variety of missions, including battlefield assaults, search and rescue, stealth, sabotage, vehicle chases and tank battles. Heeding the call of duty, gamers step into the boots of a U.S. paratrooper, a British commando and a Russian infantryman as they take on the Nazi War machine through pivotal World War II battles and authentic military campaigns
