The definitive edition of G.rev’s military vertical scrolling shooter, UNDER DEFEAT, has arrived.
- After the total war, what will the soldiers witness? It has already been over a decade since the war between the Empire and the Federation, which divides the continent, began. Both sides, having reached the peak of exhaustion, begin to approach each other and agree upon a ceasefire date. In anticipation of the upcoming ceasefire, new weapons and prototypes are continually deployed… An unprecedented battle is now about to begin───
- Deploy in a combat helicopter and annihilate enemy weapons with anti-air and anti-ground attacks: Players can choose from four combat helicopters to deploy. Using shots that serve both anti-air and anti-ground purposes, maneuver to aim, and sometimes close in rapidly on the enemy for an attack. Execute missions with simple yet multidimensional control techniques and strategic stage progression. Experience a realistic “battlefield,” with allies falling amidst fierce battles against various weapons and communications flying back and forth between friend and foe alike.
- Take on the frontlines repeatedly with a variety of engaging game modes: Includes three game modes—”NEW ORDER,” “NEW ORDER+,” and “Arcade”—each with different screen sizes, stage structures, and game rules. Practice your favorite stages and record replay footage in “Training” mode, then compete with players nationwide in “Online Rankings” for a score attack challenge. Additionally, the “Gallery” mode unlocks in-game illustrations and materials based on your gameplay progress.
- With abundant options and the new BGM set “BOOSTED,” the battlefield becomes even more intense: Equipped with features such as “DUAL STICK” controls for switching shot operations, subtitles for in-stage radio communications, and on-screen displays of contribution levels and rank during gameplay. Also includes the new BGM set “BOOSTED,” composed by Shinji Hosoe, the original composer for UNDER DEFEAT, and other members of SuperSweep. Play with your favorite BGM version, including tracks from past releases.
