The harsh battle of the girls who awakened as Exsia against the Nephilim who appeared from another world begins... Celestial Machina: Exia in the Twilight" is a powerful 3D real-time tactics game! Formations are formed by combining various units. ◆Story  Suddenly, a bottomless pit called "Absos" appeared in the far north. The Nephilim appeared from there, and the human race was in unprecedented danger. Humanity fought back with aerial battleships, but they were gradually being driven back. However, thanks to the unknown power of the Einhoff Soul (Infinite Light), they succeeded in developing and operating a "humanoid battleship," a fusion of an awakened girl and a flying battleship. The "Armageddon", a campaign against mankind by these "Excia" and their allies, has begun. ◆Game System  Formations are formed by combining various battleship units such as flagship, cruiser, destroyer, attack ship, missile ship, support ship, and heavy cruiser. Real-time tactical combat with ring-gauge commands! All battles are presented in powerful and beautiful 3D graphics! Enjoy the powerful visuals of beams, missiles, machine guns, and blasters flying about. ◆Attractive Characters  All characters are rendered in cartoon-like 3D, and can be customized with costumes, accessories and more! Additional features to be added in future updates  Field exploration and interaction   We are planning to add a system that allows players to freely walk around the field with their favorite characters and enjoy interacting with various characters.

ReceptionRating · Positive reviews · Number of ratings

Celestial Machina holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DarkSlayerXGunbird2 has 33 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of DarkSlayerXGunbird2's written reviews are positive against 0% of Celestial Machina's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DarkSlayerXGunbird2 ships an update fortnightly, Celestial Machina every 2 weeks. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
