Unreal Multiplayer Architect

Unreal's replication model is powerful but unforgiving, get actor replication, RPCs, or the GameMode/GameState split wrong and you end up with state that's inconsistent between clients, exploitable client-authoritative logic, or a dedicated-server setup that doesn't actually scale under real player counts. We architect the replication graph, the GameMode/GameState hierarchy, and the dedicated-server deployment so gameplay state stays consistent and cheat-resistant, and we test it under realistic player counts and network conditions rather than a two-machine LAN test. Studios need this when multiplayer state desyncs in ways that are hard to reproduce, when a dedicated-server setup exists but hasn't been load-tested, or when replication bandwidth is spiraling as player count grows. We deliver an architecture your team can extend without reintroducing the same desync bugs.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Review the current replication setup and GameMode/GameState structure for the sources of desync or exploitability.
2
Rebuild or extend the replication graph for one core system and load-test it under realistic player counts and latency.
3
Review desync, bandwidth, and cheat-surface findings with your engineering team before extending the pattern further.
4
Roll the architecture out to the full game with dedicated-server deployment tuned for your expected concurrency.
