The third installment of The Journeyman Project adventure game series utilizes a 1st person perspective with a panoramic view you can rotate in 360 degrees freely. The game casts the player as Gage Blackwood, Agent 5 of the Temporal Security Agency, who must travel back in time visiting Atlantis, El Dorado, and Shangri La. Your mission is to capture a rogue TSA agent, Agent 3, and collect several mysterious artifacts left by an ancient alien race. These artifacts help to protect Earth from an alien invasion and save time and reality itself.
New to the third game is the Chameleon Suit. No longer must the player avoid being seen while traveling through the past, as they can now disguise themselves as any person they have seen. People in the past can be spoken to, and their reactions vary based on who Gage is disguised as. Puzzles often need to be solved by bringing in items from another time or talking to a character to learn more about mythical societies.
