Escort map objectives require escorting a payload vehicle through the map to a destination before a timer expires.
There is an attacking and defending team. The attacking team escorts the payload across the map, the defending team stops the payload.
Each attacker within range, up to a maximum of three, will increase the payload's speed. If the defending team is in range of the payload, the payload wont move forward.
If the attacking team is 10 seconds not in range of the payload, it is moving backwards.
Along the way, the escort may reach checkpoints that add time to the attacking team's game timer. Once the payload has reached such a checkpoint, the defending team cannot move the payload further back than that checkpoint.
