All systems are ready to go, Liberators! To make sure that you’ve got optimum control over the skies, we’re introducing another new feature – Plane Tier! Accessed through your base’s Control Tower, Plane Tier can shoot your plane’s stats to the moon! The Air Supremacy menus allow you to perform all of your plane maintenance. By upgrading your plane tier, you can upgrade your stats on a percentage scale! Propellers and Plane Parts directly increase your plane’s numerical stats, so only the most elite Liberators will balance all aspects of their plane’s abilities! Tier upgrades can be performed by acquiring Plane Prints, available through Special Events, or by facing off against the Reichstagitself! Keep on fighting Liberators. These Plane Tiers won't upgrade themselves! The greatest multiplayer army game of the year has just gotten a little hotter! Play online for free today! Can't get enough great games?
