Many gameplay features from the original Lost Planet game are present. Recurring elements include major boss battles, extreme terrain, and the ability to pilot mechanized armor suits, known as Vital Suits (VSs). On July 24, 2009, at Comic-Con 2009, producer Jun Takeuchi held a Q&A session for fans. Takeuchi revealed that there would be a lot more co-op based VSs.[8] Players will be able to ride on the sides of some VSs. These VSs can be controlled by one player, while two others hang on by the sides and shoot. Takeuchi also revealed that there would be flying VSs which feature unlimited flying time.[8]
