The game has 22 missions to complete, with upgradeable World War I-era planes, including Snoopy's Sopwith Camel, to control. Unlike the original comic, many Peanuts characters appear in the game as officers and pilots for the Royal Flying Corps. The main characters include Charlie Brown, Lucy, Linus, Sally, Peppermint Patty, Marcie and more. There are also several enemies for Snoopy to shoot down, including the Baron himself.
