// CASE STUDY · ATONE · 2021–2026

Five years, every discipline, one game.

ATONE is the MMORPG GS Studio™ built — custom dedicated servers, 70 CCU per layer, UE5 IRIS, Nanite, and Mover running in a real game loop. Concept, character, level, animation, UI, VFX, and technical art — all built in-house. The portfolio and the proof of work for everything we offer.

// 01 WORLD

A place that has to run at scale.

Environment art authored against streaming budgets, LOD ceilings, and seamless seventy-CCU layers. Beauty that survives the tick.

Ornate torch-lit temple interior with horned idol on a dais, rugs, and ritual candles — Temple of Iblis — throne

Stone relief of warriors carved into a shrine wall, lit by twin braziers over rubble-strewn floor — Carved relief shrine

Inside a sand-floored cave, a torch-lit gate leads deeper past a lone tent and fallen banners — Melisir — cave gate

// 02 CHARACTERS

Concept to engine. Same image, no surprises.

Concept art on the left, the same character standing in UE5 on the right — the silhouette, palette, and intent survive the pipeline. That's what production-ready means.

// 03 UI & VFX

Readable UI. Readable effects.

Game UI and VFX tuned for live-service contexts and crowded networked scenes — not single-player cinematics. The difference matters.

// 04 ANIMATION

Motion that networks.

Gameplay animation authored with replication, prediction, and server-authoritative motion in mind.

// 05 NUMBERS

Production stats. No rounding up.

The ATONE team built every discipline in-house over five years — which is the claim, in numbers, behind everything on the art and engineering pages. These are real production stats from a live MMO, not pitch-deck aspirations. Server tick cost down ~35% after the IRIS migration. Movement bandwidth down ~60% after the Mover delta codec. The 70-character anim scene fit in ~2.5 ms (was 8–10 ms) once we lifted pose evaluation onto compute shaders. The full breakdown is in the technical post-mortem.

Every frame, every bone, every particle — paid for in production, not in a pitch deck.

About this project:ATONE was developed by GS Studio™ for an external client across five years (2020–2026). The project is currently on hold pending the client's capital review. GS Studio™ handled every discipline — engineering, art, design, UI, VFX, animation, technical art — end-to-end. The technical work is described in detail in the technical post-mortem.
