Control mode returns in destiny 2, it pits two teams that are trying to capture and hold up to 3 zones around a map against each other. Basically you are rewarded points for taking control of a zone or for killing an enemy. You can increase the number of points you recieve by zones controlled. The points you recieve are as follows:
1 Point for claiming a zone’s control point.
1 Point for killing an enemy.
2 Points for killing an enemy while your team controls the majority of zones.
3 Points for killing an enemy while your team controls all zones.
The winner of Control mode is determined by the first team to reach 100 points or the team that has the most points when the match timer reaches 8 minutes.
