A laptop spawns somewhere on the map. The players' goal is to capture the laptop for your team. If one team captures the laptop, they must defend it from being re-captured (and therefore destroyed) by the opposing team. The team that has captured the laptop does not respawn, whereas the team that is attempting to re-capture it respawns normally.
For every 5 seconds a laptop remains under a team's control, that team scores 5 points. To capture/destroy a laptop, the player must stand in a defined area near the laptop (usually one must stand in the same room it is in). If multiple players from the same team are within this area, the laptop is captured more quickly.
A new laptop spawns after the old one has been re-captured or when the team holding the laptop does so for a preset amount of time, whichever comes first. The first team to capture the laptop has the advantage, for the new HQ always appears closer and easier to access to the dominating team. This can however be neutralized to an extent by spreading out to where the laptop may spawn next, preventing the enemy (who just caught it) from spawning right by it.
