In PlanetSide, there’s just one big map that never resets.

The team I played with would try to bring the front line to a bridge before logging off for the night. Bridges were notoriously difficult to cross, so you could count on no major territorial changes happening while you sleep. The zerg was content to snipe across the bridge all night, and when organized Ops resumed the next day, the bridge would simply be bypassed by mass airlift.
