Spike Three Multiplayer Backend Patterns and Recommend One
Overview
What this challenge is about.
Implement authoritative, lockstep, and hybrid multiplayer patterns in Rust/Go, benchmark them, and earn a verifiable certificate.
The scenario
The studio is a venture-backed cooperative-game startup in Helsinki with about 20 staff and one unreleased title; a wrong architecture choice now means rewriting the netcode after launch, when 60,000 concurrent players make mistakes expensive and visible.
The Brief
What you'll do, and what you'll demonstrate.
The studio must choose one of three real-time multiplayer backend patterns before committing six months of work, and the decision needs measured bandwidth, server-cost, and responsiveness evidence rather than opinion.
Earning criteria — what you'll demonstrate
- Translate gameplay constraints into measurable backend requirements
- Build faithful minimal versions of three competing real-time networking patterns
- Design and run a controlled load benchmark with simulated network conditions and reproducible numbers
- Write an evidence-cited architecture recommendation a technical leader can act on
- Sequence a 90-day plan that reduces the highest-risk parts of the chosen pattern first
