游戲<公主同盟:圣劍武勇傳>原聲由 足立美奈子(作曲) 林 茂樹(編曲)。
Sting即將于12月份在NDS平臺上正式推出這款《公主同盟：圣劍武勇傳》（ユグドラ・ユニゾン～聖剣武勇伝～）的戰略游戲。這次《公主同盟：圣劍武勇傳》作品是2006年Sting于GBA平臺上及2008年于PSP上推出的《公主同盟》外傳性質的作品，本次外傳作品曾于2007年于手機平臺上推出過，而這次將會重新制作并且以新的形態在NDS平臺上推出。

《公主同盟：圣劍武勇傳》除了繼承原作《公主同盟》的系統以外還將大幅度追加新要素及在本次《圣劍武勇傳》內才會出現的角色、敵對關系及歷史事件等等，同時本次游戲的戰略系統改成為即時戰略系統，玩家需要在緊張的戰斗中隨時分析敵方行動，并且正確地給出命令來取得戰斗的勝利。

整個游戲的流程將大致分為3個部分，選擇勢力范圍、戰爭、占領對方勢力并重新分配軍力等。玩家首先要在游戲最初提供的兩大勢力范圍“凡塔吉亞王國”（即公主尤古多拉勢力）、米拉諾盜賊團（即原作男主人公盜賊米拉諾勢力）進行選擇，然后和其他的勢力范圍開展斗爭。
