Our take on Aeternum

The academy mystery gives the shooter a story frame, but the available modes also let players set dialogue aside or remove shooting altogether. The central play remains about navigating bullet patterns, with five stages and eight boss fights defining its scope.

What is Aeternum?

Aeternum is a side-scrolling bullet hell shooter set at Aeternum Academy, where Ellica searches for her missing friend Macy and other absent students.

Story Mode combines the mystery with combat, while dialogue can be turned off for a focus on dodging bullets. Enemies attack in waves, and boss fights use scripted bullet patterns. The game has five stages, eight full boss fights, and five difficulty levels ranging from Easy to Lunatic. Arrange mode offers a scoring-focused challenge, while Pacifist Mode prevents Ellica from firing back. The game includes a 17-track chip-pop synth soundtrack, with the full soundtrack available as free DLC.
