Special Agent 4

This level is my favorite in the Agent Series. The interaction between R and B is very dramatic. The purpose of this level is to test Autopilot of different routes at the same starting point, and only if the 1 route is taken can the 2 route be triggered.

Autopilot，Low Ceiling，Half Block with R is needed. In vedio I use a cool trick to make B ride R, but autopilot also work.

Spoiler: Hints

The starting point is the metal stair and the ending point is the metal under the tower. Autonpilot up to save R. Go back to the metal stair, and take the river as the end point, and then autopilot to the bridge to meet R. Ride R, and let R stagger half the block by the Draggable. R will carry B to the end side. Get off R and use autopilot for the last time and reach the end point under the interference of R.
