I will build multiplayer replication with server authority
Ironwake
About this gig
Hello amazing buyer,
Your game can be fun when players fight AI alone but eventually, some players may want more. They want to invite a friend, work together, compete, share unexpected moments, and experience the game together. That social experience can make a game feel more engaging and give players another reason to come back.
But the moment another player joins, the technical challenges begin. One player sees an action that the other doesn't. Variables disagree, events execute on the wrong machine, movement feels delayed, or an apparently simple feature becomes a replication problem.
That's where a solid multiplayer architecture matters.
We can work on:
- Replicated variables with correct RepNotify handling
- Server RPCs with authority and ownership checks
- Gameplay state and event replication
- Converting existing single player systems for multiplayer
- Client side movement prediction
The goal isn't simply to add Replicated to a few variables. It's to make the agreed system behave correctly across multiple players and give you a clear technical handoff.
Send your UE version, existing system, multiplayer setup and the problem you're seeing

FAQ
Can you convert my single-player system to multiplayer?
Yes. That's a core use case. The existing system must be provided for review so the exact conversion scope can be confirmed
Can you fix RepNotify and RPC problems?
Yes. We can inspect replicated state, RPC authority/ownership and client/server execution for the agreed system
Do you build the entire multiplayer backend?
No. This Gig covers Unreal networking inside the agreed existing system, but full backend infrastructure or an entire multiplayer game can be done
Can you guarantee zero latency or desync?
No honest developer should. We correct scoped replication and authority problems and test the resulting behavior
