I will integrate multiplayer mirror, fishnet with steamworks sdk in unity
Semih Taha A.
About this gig
Are your players teleporting through walls? Is your Unity multiplayer project suffering from lag, desync, or broken RPCs? Or do you need a seamless Steamworks matchmaking integration?
Multiplayer game development is fundamentally different from single-player. You don't just need a coder; you need a network architect. Whether you are using **Mirror**, **Fishnet**, or need a flawless Steamworks API integration, I will engineer a robust, server-authoritative foundation for your game.
What I Can Do For You:
- Steamworks Integration: Matchmaking, Lobbies, P2P networking, and friend invites.
- Fishnet & Mirror Expertise: Advanced setup, migration, and SyncVar/RPC implementations.
- Server-Authoritative Logic: Anti-cheat architecture, secure variable syncing, and server-side hit detection.
- Bug Fixing: Eliminating latency issues, desync, and player ghosting.
- Optimization: Low-level C#/C++ optimizations for Linux-based dedicated servers.
Why Choose Me?
I write clean, scalable, and documented code. I don't use band-aid fixes; I solve the root cause of your network bottlenecks.
️ ATTENTION: Multiplayer scope varies wildly. **PLEASE MESSAGE ME BEFORE PURCHASE**

FAQ
Can you build a massive MMO like World of Warcraft or PUBG?
No. Building a true MMO requires a massive studio and budget. I specialize in session-based multiplayer games, co-op games, and arena shooters (typically up to 32-64 players depending on the game logic).
I already have a single-player game. Can you just "add multiplayer" to it?
Converting a single-player game to multiplayer isn't a drag-and-drop process; it usually requires rewriting the core architecture and player controllers. Please message me first so I can review your codebase and give you a realistic custom quote.
Do you provide server hosting (AWS, Multiplay, Azure)?
My gig covers the network engineering and coding. Server hosting costs are your responsibility. However, Steamworks P2P lobbies are free. If you need dedicated server setup on AWS/Azure, I can provide that as a Custom Extra.
Which networking solution should I choose: Mirror, Fishnet, or Netcode for GameObjects (NGO)?
It depends on your specific needs. Fishnet is incredibly fast and great for server-authoritative logic. Mirror is highly stable and documented. Send me your game design document or idea, and I will prescribe the best tech stack for your project.
Will you sign an NDA to protect my game idea?
Absolutely. Your intellectual property is safe. I am completely open to signing a standard NDA before we dive into the technical details of your project.
