About RELLION: NPC Survival

Rellion: NPC Survival is Daeri Soft's idle gacha RPG with a premise — the players have vanished from a fantasy MMO and only its NPCs remain, looping until you arrive as the one True Player — and an AFK Arena-style body: auto-battles, formations, a relay system that swaps squads mid-fight, and offline growth. Free on iOS and Android since May 2026 with ads, loot boxes and Blue Gems from $3.99 to $79.99. It rates 4.6 on the App Store and 4.4 on Google Play. Reviewers call the pulls generous; they also report a chapter-two paywall and content exhausted in three days.

Rellion Review: A Clever Premise on an Idle Gacha, Empty by Day Three

The Players Left. The NPCs Kept Looping. You Are the One Who Came Back.

The story hook is better than the genre usually gets: Rellion is a forgotten game world whose players disappeared, leaving NPCs to run aimless quests through 900 loops of the same fading realm, until you log in as the True Player whose choices decide whether it survives. What you do with that is AFK Arena: recruit NPC heroes — an SSR on first log-in — build a team and a formation, and let battles play out automatically, with a relay system that sends a second squad in when the first falls and traits that the listing says can flip an outcome. Growth runs while you are offline and is claimed in a tap; dungeons and multi-boss raids are the endgame. A September 16, 2026 Play four-star calls the game fine, likes the auto-battler play, and counts 60 to 80 pulls a day from the currency even late on — very generous, in its words.

Empty in Three Days, a Wall in Chapter Two, and Enemies Tuned Too High

The content complaint arrived within days. A May 17 App Store one-star had completed the maximum levels of everything after three days and was left with dailies and a banner that was not even a new hero; no guilds, no PvP — a shell of a game. A June 9 one-star says the studio has pumped out power-creeping characters instead, starving players of currency to keep up, with a separate equipment gacha on top. The difficulty split is the other thread: a September 4 Play one-star with five votes cannot finish chapter two without hitting the paywall and objects that the assets are AI-generated, so the greed is unearned; a June 25 three-star at chapter five with level-60 characters is still destroyed by enemies it thinks belong in chapter seven. An August 18 three-star was stuck in an update loop with no update to install; a May crash cost another player their gems.

Blue Gems to $79.99, Lifetime Pensions, an Ad Removal Pack, Loot Boxes

The shop is standard Korean idle-gacha: Blue Gem bundles from 1,000 plus 500 for $3.99 to 20,000 plus 10,000 for $79.99, Lifetime Gem and Summon Ticket Pensions at $14.99, and an Ad Removal Pack at $5.99; Google Play's range is $0.99 to $79.99, and Apple flags Loot Boxes and Advertising. The ads are the rewarded kind that the removal pack silences. Data collection is fuller than average: Google lists personal info, app info and device IDs collected, with location, app activity and device IDs shared; Apple lists location and identifiers not linked to you. The iOS build is 1.32 GB on iOS 15 or later; Android needs 7.1; thirteen languages; rated Everyone 10+ and 13+. Four months in it shows 100,000-plus installs and 13,300 reviews at 4.4 on Play, and 91 App Store ratings at 4.6. Prices are regional.

Pros

A premise with wit — a dead MMO's NPCs, looping, waiting for one player
Sixty to eighty pulls a day from free currency, per a September four-star
Relay battles and formations that give the auto-fights a decision or two
Offline growth claimed in a tap, and dailies built to be quick
Thirteen languages and an update every few weeks

Cons

Content exhausted in three days — no guilds, no PvP, per May reviews
A paywall by chapter two and enemies tuned above their chapter
Power-creep heroes, currency starvation and a second gacha for gear
AI-generated assets, per a September one-star, and an update loop that locked a player out

Verdict

A 5.1: a premise worth a better game — the NPCs of an abandoned MMO on their 900th loop — attached to an idle gacha that gives generously, walls early, and had a player finish everything in three days. Take it for the story hook and a week of free pulls. Skip it if you want guilds, PvP or a chapter three you can reach without paying.

Gameplay5AFK Arena's loop with a relay twist; no strategy needed beyond feeding resources, says the top critic.

Controls7Tap, claim, deploy — idle controls that do their job.

Replay value4Everything maxed by day three for one player; banners and events since, guilds and PvP still absent.

Graphics & sound6Pretty anime illustration and skill effects, with a reviewer's credible claim that some of it is AI.

Monetisation4Generous pulls up front, then a chapter-two wall, $79.99 gems, pensions and an ad-removal pack.

Frequently asked questions

Can you play Rellion offline?

The growth happens offline — resources accumulate while the app is closed — but claiming them, battling, summoning and events all need Daeri Soft's servers, and an August 2026 reviewer was locked out entirely by an update-check loop. Treat it as an online game that rewards you for being away.

Is Rellion pay to win?

The pulls are generous — 60 to 80 a day, per a September 2026 player — but the wall is progression: a September one-star could not clear chapter two without paying, a June three-star was stuck at chapter five with maxed heroes, and a June one-star describes currency starvation from power creep. Blue Gems run $3.99 to $79.99 with loot boxes flagged. Prices vary by region.

What phone do you need for Rellion?

iOS 15 or newer with 1.32 GB free, or Android 7.1 or newer. It is a 2D idle game and no reviewer complains about performance; a May 2026 crash cost one player their gems, and the August update loop on iPhone was a store issue rather than a hardware one. The game runs in thirteen languages.

Can you play Rellion with friends?

Not yet in any structured way: May 2026 reviews list no guilds and no PvP among the missing features, and the multi-boss raids in the listing are the closest thing to group content. Google Play notes that users interact, which covers chat and the Discord community rather than co-op.

How much time does Rellion take?

By design, minutes a day — dailies are fast and growth is automatic — and by one May 2026 player's account, three days to exhaust the content. Since then the calendar is banners, a 100-day event and new heroes, so the game is a daily check-in for anyone who stays.
