GRAZE TO GROW STRONGER The aurora barrier that shielded the world โ€” the Neon Sky โ€” has been torn open by a dimensional rift. Machine legions pour through. Only one force stands against them: pilots whose cores resonate and grow stronger the closer they graze danger โ€” the Wingmates. Beneath the broken sky, they are all that remain. โ–  Graze to Grow Stronger Don't just dodge the bullets โ€” graze them! The closer you fly to danger, the harder your core resonates and the stronger your firepower becomes. Risk becomes reward. A thrill you won't find anywhere else. โ–  Nineteen Wingmates That Live and Breathe No static portraits here. Seraph, Guardian of the Heavens. Nova, the Falling Star. Ragnarok, Shadow of the End. Umbra, the Veiled Prophetโ€ฆ Each wingmate breathes, moves, and fights at your side โ€” with a story of their own. โ–  A Journey from Earth to the Origin EARTHFALL. ASCENSION. INCURSION. DOMINION. GENESIS. From the invasion falling upon the earth to the very origin of the rift โ€” an epic journey to reclaim the broken sky. โ–  Depth That Keeps On Giving Forge upgrades, skill trees, codex evolution, ascension ranks. Excavate named relics, climb the endless floors of the Abyss, and take on weekly mutation challenges. The deeper you go, the more builds you unlock. โ–  Easy to Pick Up, Hard to Put Down One-handed portrait controls โ€” play anywhere, anytime. But don't let that fool you: the depth is anything but casual. Beyond the rift โ€” together. โ€ป This game includes randomized (gacha) items. Drop rates are available in-game and on the official website. Official site: https://neonsky.alwayscorp.co.kr Support: support@alwayscorp.co.kr
