Marco Cloud (マルコクラウド Marukokuraudo ) is a pilot for the American government organization AMS. He is a supporting character in Zombie Revenge, assisting fellow agents Stick Breitling, Linda Rotta and Rikiya Busujima in their fight against the bioterrorist ZED.
He first appears in a helicopter to rescue the agents from an explosion at a chemical plant. During the ensuing fight he will also drop ammunition to aid the players. After the agents hop on board, he takes them toward a runaway train loaded with explosives and the virus responsible for the outbreak, and is set to crash.
Marco doesn't appear again until the game's ending, picking up the agents in the desert after ZED and the Black Magician were destroyed. He urgently tells his fellow agents, "now he's highjacked a ship!"
