The third game sees players take on the role of Prophet as he returns to New York, only to discover the city's been encased in a giant Nanodome created by the corrupt Cell Corporation. The New York City Liberty Dome is a veritable urban rainforest teeming with overgrown trees, dense swamplands and raging rivers within the Liberty Dome, seven distinct and treacherous environments become known as the Seven Wonders. Set in 2047, Prophet is said to be on a "revenge mission" after uncovering the truth behind Cell's motives for building the quarantined Nanodomes. "The citizens were told that the giant citywide structures were resurrected to protect the population and to cleanse these metropolises of the remnants of Ceph forces. In reality, the Nanodomes are CELL's covert attempt at a land and technology grab in their quest for global domination. With Alien Ceph lurking around every corner and human enemies on the attack, nobody is safe in the path of vengeance. Everyone is a target in Prophet's quest for retribution."
