Server-Side Fog of War: Defending Against Wall Hacks | Unreal Fest Stockholm 2025
In this session recorded at Unreal Fest Stockholm, CCP Games presents a server-side system they’ve dubbed “Fog of War” that stops wall hacks at the source by ensuring clients only ever receive what their player should legitimately know. No line of sight? No data. No exploit.
CCP walks through the problem, shows how they solved it for EVE Vanguard, and demonstrates how they integrated the solution on top of Unreal Engine's replication graph.
If you care about fair multiplayer experiences, this talk is for you.
