Aetheris Core

Aetheris Core is a fast-paced top-down sci-fi survivors-like (bullet-heaven) roguelite where each run turns a fragile ship into a storm of weapons, relics, and hard-won survival tools. Cut through enemy waves, build around powerful synergies, and face bosses that test both your loadout and your movement.

• 15 attack abilities to unlock, combine, and scale
• 28 upgrades and 39 relics that push each run in a different direction
• 10 major boss encounters with multi-phase fights and learnable mechanics
• Unique hard-mode boss variants that remix the fights instead of only raising stats
• 8 pilots with distinct ships, starting tools, and progression paths
• Permanent Core progression powered by Aether Seeds earned in runs
• Unlockable pilot and ship skins for long-term goals and customization
• Multiple endings for players who push deeper into the Core's story

Build The Run Around Your Choices

Choose attack abilities, stack upgrades, collect relics, and shape each run around burst damage, sustained area control, survivability, speed, or strange late-run synergies. A run can begin with a simple weapon and end as a screen-filling build you assembled piece by piece.

Bosses With Real Mechanics

Aetheris Core features 10 major boss encounters, from agile duelists and summoners to multi-part constructs, arena-control fights, and late-game set-piece battles. Bosses are built around readable patterns, phase changes, and mechanics you learn rather than raw stat walls.

Hard Mode Changes The Fight

Hard-mode bosses are designed as remixed encounters, not simple HP-and-damage bumps. Expect altered behavior, tighter punish windows, new hazards, faster pressure, retaliating objectives, and variant attack patterns that ask you to master the fight in a different way.
