WHAT WE DOProduct, platform and AI engineering connected through explicit contractsGAME & IMMERSIVE · BACKEND & CLOUD · AI ENGINEERING

SELECTED TITLES

Original productions, commissioned builds and shipped titles from the people on this team.

CLIENT · CONTRACTS · ONLINE SYSTEMS

Two production disciplines.
One explicit integration boundary.

The player-facing product and the systems behind it remain independently owned, connected through stable APIs, realtime protocols and shared release contracts.

We design and build the player-facing product, from gameplay systems and interaction to rendering, audio, content and platform-specific delivery.

Interaction

CREATE THE EXPERIENCE

Unity Game Development

We create the part players see, feel and control. Our Unity team turns concepts into production-ready games and immersive applications across PC, console, mobile, VR and AR.

POWER THE EXPERIENCE

Backend & Online Systems

We engineer the systems behind the screen: multiplayer, matchmaking, player services, dedicated servers and cloud operations designed for real traffic, observable failures and controlled operating cost.

PLATFORM RANGE

Built for the surface the product actually lives on.

Every tile is a production our team designed, engineered or led — from desktop releases to headset-native and location-based experiences.

Player-facing development and backend engineering are separate production disciplines.

The game client owns presentation, interaction and moment-to-moment player experience. Online systems own shared authority, identity, persistence, sessions, deployment and scale.

We connect both sides through stable contracts, testable interfaces and shared release milestones.

Bad Goons

Bad Goons

A flagship multiplayer FPS built around a battlefield players can destroy, excavate and rebuild during every match. Fully networked voxel destruction, dynamic capture points, construction and fortification, deployable spawn networks, procedural maps, tactical support assets and a broad arsenal create shifting front lines instead of static cover. The playable Early Access build is in active development toward its planned December 2026 Steam release, supported by shared developer-and-community playtests.

EXPLICIT BOUNDARIES · SHARED RELEASE PLAN

From player experience to production infrastructure.

The client and backend are not one codebase or one discipline. They are connected systems with different constraints, failure modes and release responsibilities.

We design the boundary early, so each side can evolve without turning every change into a complete-stack rewrite.

SEPARATE WORKSTREAMS · SHARED RELEASE RESPONSIBILITY

A clear path from idea to production.

Start with technical discovery
PHASEGAME DEVELOPMENTBACKEND & ONLINE SYSTEMS
  1. 01

    Product Discovery

    Audience, game loop, platforms and performance budgets.

    Online requirements, traffic assumptions and launch constraints.

  2. 02

    Experience Definition

    Gameplay, interaction, client architecture and content workflow.

    Contract inputs: shared state, authority and client versioning.

  3. 03

    Online Architecture

    Client integration points and network-visible game rules.

    Protocols, player data, sessions, servers, deployment and scale.

  4. 04

    Parallel Production

    Regular playable builds against stable test interfaces.

    Integration environments, telemetry and measurable milestones.

  5. 05

    Integration & Launch

    Profiling, platform validation and release readiness.

    Network/load tests, automation, recovery and observability.

  6. 06

    Live Evolution

    Gameplay iteration, content updates and player telemetry.

    Backend evolution, live support and infrastructure cost tuning.

WHY BACKEND ALCHEMIST

Different specialists.
One accountable direction.

01

Game-first engineering

We evaluate the game loop, player feel, interaction, content workflow and platform constraints before choosing the technical solution.

02

Distinct disciplines. Shared accountability.

Different specialists and success criteria, connected by one architecture, delivery plan and accountable technical direction.

03

Senior by default

Technical leaders stay close to architecture, implementation and delivery from the first call.

04

Production over prototypes

Deployment, monitoring, recovery, maintainability and support remain part of the build.

PRACTICAL QUESTIONS

Clarity before the call.

Can you build only the game client?

Yes. Game Development is scoped and estimated as its own player-facing production discipline.

Can you build only the backend?

Yes. We can own multiplayer, backend, servers or cloud while working through explicit interfaces with your game team.

Can you develop games for PC, console and mobile?

Yes. Our Unity work covers PC, console and mobile, with platform delivery and performance planned from discovery.

Do you build both VR games and enterprise VR applications?

Yes. Verified team experience includes commercial VR games and production enterprise VR platforms.

Can you develop AR products?

Yes. We support AR products for entertainment, visualization, training, guidance and connected content.

Can you join an existing Unity project?

Yes. We begin with the codebase, production constraints and ownership boundaries before changing critical systems.

Can you add online systems to an existing game?

Often. We first assess authority, simulation, save data, versioning and deployment constraints.

When should the game client and backend be architected together?

As soon as shared state, sessions, identity or persistence affect the game loop. Early contracts reduce integration rework.

Do the game-development and backend work have separate estimates?

Yes. The disciplines are scoped separately, and development cost is also separated from ongoing operating cost.

Can one team take responsibility for both sides?

Yes. Separate specialists work through one architecture, shared milestones and one accountable technical direction.
