GS Studio™ is a co-development partner for complex game productions — engineering, art, and live-ops, proven on ATONE. Custom dedicated servers, full-stack art production, 70 CCU per layer, UE5 IRIS running in a real game loop — not a tech demo. We integrate into your pipeline inside 72 hours and ship under your brand.
A co-development partner for complex game productions — the engineering, art, and live-ops depth of a first-party team, available under your brand and inside your pipeline.
Custom dedicated server architectures, authoritative state management, interest management at scale, replication tuned for 70+ CCU per layer. We've run UE5 IRIS in production and know where the sharp edges are — because we hit them first, building ATONE. Whether you're standing up a new server stack or inheriting one buckling under load, we come in with the experience and the reference implementations.
Ambitious multiplayer projects fail on content velocity as often as they fail on tech. We scale your production — gameplay engineers, systems designers, tools programmers, animators, environment and character artists — inside your existing pipeline. Your version control, your processes, your review standards. No parallel org. No black-box delivery. Your leads review our work the same way they review internal work.
Most outsourcing asks you to contort your project to fit the vendor's process. We do the opposite. Dedicated squads, embedded individuals, milestone-based delivery, or full co-development of a vertical slice or feature track — we structure the engagement around how your team already works. Our people work under your brand, attend your standups, and are accountable to your producers. And we're in the pipeline in 72 hours — not 72 days.
Shipping is the middle of an MMO's life, not the end. We support live games with feature development, content cadence, server operations, performance work, and the unglamorous engineering that keeps a multiplayer game healthy. We've done this for five years on the MMORPG we built — server tick down ~35% after the IRIS migration, movement bandwidth down ~60% after the Mover delta codec. Shipping work, not pitch deck.
Four weeks. Fixed fee. The unvarnished read on whether your multiplayer stack is going to ship — run by the team that spent five years building a UE5 MMORPG to 70 CCU per layer with Souls-tier combat fidelity. IRIS, Mover, GAS, custom dedicated servers, GPU-accelerated animation. The audit you'd run yourself if you'd already shipped it. See the audit →
Vertical ownership of one UE5 multiplayer system. Six months. Senior staffing. Fixed price. Five engineers, one vertical, owned end-to-end — replication, GAS, animation pipeline, dedicated server, or a system you name. Senior-led, embedded in your Perforce, accountable to your producers. The middle path between hiring senior FTEs you can't find and an outsourced T&M team you can't trust to ship. See the Pod →
ATONE is the MMORPG we built. Five years of decisions, rewrites, performance cliffs, and recoveries — a real game loop running custom dedicated servers, 70 CCU per layer, GPU skinning for dense scenes, and UE5's IRIS replication, Nanite geometry, and Mover movement system.
Every problem a partner studio brings us, we've probably hit a version of it ourselves.
That's the difference between an outsourcer who's read about MMO tech and a co-dev partner who's been in the arena. We've been running GS Studio™ since 2011. ATONE is the last five years of what we've learned — and what we bring to your project on day one.
Send your stack, your target scale, and the problem you're stuck on. We'll respond with a concrete proposal — not a sales deck.
