Playing War Wings with friends makes it that much special.
In order to do it, just add friends through the game's Friend system. You can form teams and carry out battles with those players, either in a two-pilot team or a four-pilot team.
Attention: As noted on some of our social outlets, War Wings will be removed from stores as of the beginning of December. So, please refrain from performing further in-game purchases as your enjoyment of said purchases may be short-lived.
