DayZ
Drag timing, container swaps, relogs, and hand-state bugs have repeatedly allowed players to duplicate ammunition, gear, and building supplies. DayZ has seen many dupe waves.
Logging out near a base and reconnecting from another server or shard can let raiders appear past defended angles. This server-hop entry method is infamous among base builders.
In third person, players can scout around walls and windows without exposing themselves. It creates a built-in information exploit on servers that allow the camera mode.
Specific vault or crawl interactions can push players through fences, gates, or unfinished base geometry. These clips undermine base security and choke points.
Managing weight by rapidly moving gear between hands, containers, or dropped states can temporarily ease travel or combat pressure beyond intended stamina tradeoffs.
