Along with the new planes and maps, two additional gametypes are available for download: Chicken Pox and Gunheist. Capture the Flag takes on a whole new twist in Gunheist, in which teams are challenged to capture and hold three anti-aircraft gun emplacements within a limited time. In Chicken Pox, gamers have to capture chickens and use them as power-ups. A plane carrying a chicken will enjoy a full boost recharge, rapid damage recovery and instant reloading of its secondary weapons, making it the deadliest chicken delivery system in the sky and awarding the pilot with two points for shooting down any chicken-less pilots.

Combining thrilling dogfights with the swashbuckling style of a Hollywood action-adventure movie, Crimson Skies: High Road to Revenge raises the bar for aerial combat. Set in an alternate 1930s world of gunship diplomacy and sinister intrigue, gamers pilot powerful aircraft against nefarious air pirates and behemoth war zeppelins. Crimson Skies: High Road to Revenge for Xbox is also armed to the teeth with full Xbox Live support. Up to 16 players can battle online or by System Link in an array of game modes including Dogfight, Team Dogfight, Flag Heist, Wild Chicken, Keep Away and Team Keep Away.
