Mission 13 is located on an elevated area in Area 3 on the left side of the area. In order to reach it, the player can go left when first approaching the area, going past the brick walls. There is a ramp to get up and access it. Mission 13 should be behind the player when above the ramp.
Another way Mission 13 can be reached is by first heading to the two ramps on the right side of the area. The player needs to make it to the platform, and then there should be a small wall in front of them. They will go past the small wall, go around the center of the tower, and then behind it is the kettle to Mission 13.
Moving platforms are used through this mission and often found near grates or other obstacles. These platforms are used as a type of puzzle for Agent 3 to solve. While most of the platforms are horizontal; three of the four platforms that lead to the Zapfish are vertical. The first and third platforms move at the same rate, while the second moves at a different rate.

Location: At the second checkpoint, beside the large wall. When landing on the checkpoint, you will face a large wall with moving platforms and two Octocopters overhead. Rather than engaging them, go on the path to the right. Around the corner of the wall will be three large crates. Destroy them and collect the scroll.
