Game & Immersive Development · Multiplayer systems

Online play that stays fair under real latency

We design and build multiplayer systems — netcode, matchmaking, lobbies and dedicated or relay servers — choosing an architecture that matches your genre, player counts and budget for running servers after launch.

  • Authoritative netcode
  • Lag compensation
  • Matchmaking and lobbies

Overview

The decisions behind good online play

Every multiplayer game is a trade between responsiveness, fairness and hosting cost. Letting each client decide what happened feels instant but invites cheating. Having a server decide everything is fair but feels sluggish unless the client predicts movement and corrects smoothly. Turn-based and cooperative games can use lighter models than fast competitive shooters. We pick the model from your genre, player count and tolerance for cheating, then design the game’s rules around it.

Buyers face practical questions alongside the technical ones. Do you need dedicated servers from day one, or can relays carry an early release? Should matchmaking use skill ratings, regions or simple lobbies with invite codes? How will you handle disconnects, rejoining and players on very different connections? Each answer affects both the build and the monthly hosting bill, so we model expected costs with you before committing.

Good multiplayer work is measured under pressure: simulated latency and packet loss during development, bot-driven load tests before launch, and dashboards that show server health once real players arrive. After launch, those same tools help your team spot problems early and decide when to add capacity, without guessing from player complaints alone.

Who it’s for

Built for teams like yours

  • 01

    Teams planning online play

    Studios designing a new competitive or cooperative game who need the network architecture chosen and proven before the rest of the game is built on top of it.

  • 02

    Single-player games adding co-op

    Owners of an existing game who want to add online cooperative or versus modes and need an honest assessment of what the codebase can support.

  • 03

    Games struggling at scale

    Live titles with desync, rubber-banding, cheating reports or rising server bills that need diagnosis and targeted fixes rather than a costly full rewrite of their networking code.

Why it matters

Networking decisions are hard to undo

The choice between peer-to-peer, relay and authoritative dedicated servers shapes cheating risk, hosting costs and how the game feels at 150 ms of latency. We make that call with you early, then build prediction, reconciliation and interpolation so movement and hits feel responsive without letting clients decide outcomes they should not control.

We load-test before launch, because multiplayer bugs usually appear only when many real players connect at once. Servers run in your own cloud account, with runbooks your team can follow without us.

Every engagement includes

  • Architecture reviewtopology, tick rate and hosting model chosen for your genre and budget.
  • Network prototypecore movement and interaction tested under simulated latency and packet loss.
  • Server infrastructuregame servers, matchmaking and deployment set up in your cloud account.
  • Monitoringserver health, player counts and error tracking visible from day one.
  • Load testingbot-driven tests at and above expected concurrency before launch.
  • Runbooks & handoverdocumentation for deploying, scaling and troubleshooting the servers.

Features

Multiplayer building blocks

  1. 01

    Authoritative netcode

    Server-authoritative state with client prediction and reconciliation, so play feels responsive and outcomes stay trustworthy.

  2. 02

    Lag compensation

    Interpolation, rollback or rewind techniques chosen to suit your genre, from shooters to fighting games.

  3. 03

    Matchmaking and lobbies

    Skill, region and party-based matchmaking with lobbies, friend invites and reconnect handling after dropped connections.

  4. 04

    Dedicated server hosting

    Containerized game servers that scale with demand, on hosting you control and pay for directly.

  5. 05

    Cheat resistance

    Server-side validation, rate limits and sensible trust boundaries that make common cheats harder.

  6. 06

    Load and soak testing

    Simulated players and long-running sessions that expose desyncs, leaks and bottlenecks before launch.

In practice

Multiplayer scenarios we handle

  • Competitive real-time matches

    Server-authoritative gameplay with client prediction, lag compensation for hit detection and tick rates chosen for the genre, so matches feel responsive while results stay under server control and are hard to tamper with.

  • Cooperative sessions with friends

    Lobby and invite flows, host migration or dedicated sessions, and drop-in, drop-out support so friends can join a game in progress without restarting it or losing the progress the group has already made.

  • Turn-based and asynchronous play

    Games where players take turns minutes or days apart, using backend-stored game state, push notifications and validation so moves cannot be altered, replayed or submitted out of turn by a modified client.

  • Large shared spaces

    Persistent or event-based spaces with many players, using interest management so each client only receives nearby updates, keeping bandwidth and server load within predictable limits as crowds grow during busy events.

Process

How we work

  1. 1

    Network model choice

    We compare peer-to-peer, relay and dedicated server options for your genre, decide tick rate and authority rules, and estimate hosting costs at several player-count scenarios, so the monthly hosting bill is understood before code is written.

  2. 2

    Latency prototype

    Core movement and interactions are built with prediction and reconciliation, then tested under simulated latency, jitter and packet loss so feel problems appear early, while they are still cheap to fix in the design.

  3. 3

    Session services

    Matchmaking, lobbies, invites, reconnect handling and server allocation are built or configured, with clear rules for regions, party sizes and what happens when a player disconnects or a server fails mid-match.

  4. 4

    Bot load testing

    Scripted bots connect in large numbers to measure server CPU, memory and bandwidth at and beyond expected concurrency, so capacity limits are known before launch and planned for in the hosting budget.

  5. 5

    Ops and dashboards

    Deployment scripts, autoscaling rules and dashboards for server health, match counts and errors are set up in your cloud account, with runbooks for common incidents such as a stuck server, a region outage or a bad deploy.

FAQ

Frequently asked questions

Anything else about Multiplayer systems? Ask us directly.

  1. Not always. Co-op and casual games often work well with relay or host-based networking, which costs far less to run. Competitive games, persistent worlds and anything where cheating matters usually need authoritative dedicated servers. We compare cheating risk, player experience and monthly hosting costs with you before deciding.
