COSM-GAME RELLION: NPC Survival
RELLION: NPC Survival is an idle role-playing game set in Rellion, a fading world whose non-player characters have already endured 900 failed attempts to survive. You enter as the "True Player" and build teams of collectible heroes, choosing their formation and traits to push through story stages, dungeons, and multi-boss raids. Progress continues while you are away, with offline resources feeding character growth when you return. Summoning expands the roster, while systems such as the Alchemy Gem System support longer-term progression, so the core loop alternates between collecting resources, strengthening heroes, adjusting formations, and clearing harder battles.

Platforms and availability
The Global release is available on Android through Google Play and on iPhone and iPad through the App Store. Apple also lists the iPad build as compatible with Apple-silicon Macs and Apple Vision. On Mac, Apple specifically describes the application as designed for iPad and not verified for macOS, so this should not be confused with a separately developed native Mac edition.
Gameplay and setting
Rellion is presented as a forgotten world whose NPC inhabitants have repeatedly failed to survive. The player enters this cycle as the "True Player" and takes control of teams assembled from collectible heroes.
Battle preparation centers on team composition, formation placement, and character traits. Players strengthen their roster, adjust how heroes are positioned, and send the team through campaign battles, dungeons, and encounters involving multiple bosses. Progress can continue while the game is closed through offline growth and rewards, reducing the amount of active play required for routine resource collection.
Hero recruitment uses a summoning system with SSR characters and rate-up recruitment. Longer-term progression includes systems such as the Alchemy Gem System, Equipment Codex, Chronicle content, Assault Battle, Abyss Crystal battles, and recurring dungeon and boss content.
