What We Deliver
Netcode That Holds Up
Client prediction, interpolation and lag compensation so movement and combat feel smooth on real mobile networks.
Matchmaking & Lobbies
Rooms, quick-play, private lobbies, friends, party invites and skill-based matchmaking.
Server Authority
Host/client, relay or dedicated servers with authoritative logic to stop speed hacks and cheating.
Turn-Based & Async
Card, board and puzzle games with turn-based or asynchronous play and reconnect support.
Backend & Saves
PlayFab, Firebase or custom backends for accounts, inventories, leaderboards and cloud saves.
Multiplayer Bug Fixing
Desync, ghost players, duplicate spawns and disconnect bugs found and fixed in existing projects.
Is This You?
- Your prototype works in single-player but breaks once two players join
- Players see different positions, health or scores (desync)
- You built multiplayer with AI-generated code and it falls apart under real latency
- You need to move from Photon PUN 2 to Photon Fusion or Netcode for GameObjects
- You need matchmaking, lobbies and reconnect logic for a launch
If any of these sound familiar, tell us about your project and get a plan within 24 hours.
How It Works
Choosing the right multiplayer framework
Photon Fusion suits fast action games that need client-side prediction and lag compensation. Photon PUN 2 remains a simple choice for room-based casual and card games. Unity Netcode for GameObjects fits projects that want first-party Unity support and dedicated servers, and Mirror works well for PC games with self-hosted servers. We recommend one after looking at your genre, player count, platforms and hosting budget, because changing frameworks later is expensive.
Why multiplayer prototypes break
Most multiplayer bugs come from unclear ownership of game state: two clients changing the same object, physics running differently on each device, or events arriving out of order. Prototypes built with AI-generated code often sync everything every frame, which works on a local network and fails on mobile data. We fix this by making the server or host authoritative, sending only the state that matters, and adding interpolation and prediction so the game feels responsive.
What a production multiplayer game also needs
Beyond gameplay sync, a launch-ready multiplayer game needs matchmaking, reconnection after network drops, anti-cheat checks on the server, player accounts, leaderboards and analytics. We build these with proven services such as Photon, PlayFab and Firebase so you are not maintaining fragile custom backend code.

Frequently Asked Questions
Which multiplayer frameworks do you use in Unity?
We work with Photon Fusion, Photon PUN 2, Unity Netcode for GameObjects and Mirror. We recommend one based on your game type, player count, budget and whether you need dedicated servers.
Can you add multiplayer to my existing single-player Unity game?
Yes. We audit your project, separate local and networked state, then add synchronization, rooms and matchmaking. Some systems usually need refactoring, which we scope before starting.
Can you fix desync and lag in my multiplayer game?
Yes. Desync, rubber-banding, duplicate spawns and disconnect issues are common fixes for us. We identify the root cause in your network architecture rather than patching symptoms.
My multiplayer code was written with ChatGPT or another AI tool and is unstable. Can you take over?
Yes. AI-generated netcode often works locally but fails under real latency. We review it, keep what is solid and rebuild the parts that cannot scale.
Do you build turn-based multiplayer games?
Yes. We build turn-based and asynchronous multiplayer for card, board, puzzle and strategy games, including reconnect and timeout handling.
How much does multiplayer game development cost?
Fixing or adding multiplayer to an existing game typically starts from a few thousand US dollars, while a full multiplayer game is usually $15,000 or more. We give a fixed estimate after reviewing your project.
