The mission begins with Brother Marcus informing the protagonist that Brother Aerol has been killed by a Babylon agent who is being taken to a safehouse. The protagonist must track down and intercept the transport Bus which is driving around southwest Felicity. The Bus must be taken to the docks in southeast Richman Heights (although the dialogue says Felicity), where a number of the Brethren will be waiting. After they destroy the Bus, the mission will be complete. The Bus is heading to a building in Coral City; if it can enter the garage, the mission is failed. (Sometimes the Bus can be intercepted at the southernmost point of the six-lane way, sometimes it is very close to its destination by the time the player catches up with it.)
The player will be awarded 35,000 points and a +1 score multiplier for completing the mission.
