Tesla Effect is the sixth instalment in the Tex Murphy adventure game series. The player dons the fedora of Tex Murphy, a private eye struggling to solve cases and pay the bills in a world devastated by a nuclear conflict.
The game is set in San Francisco in 2050, seven years after the cliffhanger ending of Tex Murphy: Overseer. During this time frame, Tex has seemingly abandoned his principles and has become a hard, cold-blooded man willing to take any job as long as it pays. As the game opens, Tex's office on Chandler Avenue is attacked by mysterious assailants and Tex receives a blow to the head. He wakes up, dazzled and confused, with no recollection of the last seven years. Having reverted to his older, nicer personality, Tex must now discover the truth about what happened to his girlfriend Chelsee and himself that fateful night of 2043. And of course, that will in turn lead him to uncover a sinister plot that has something to do with the research of 20th century inventor Nikola Tesla.
Tesla Effect is a first-person point-and-click adventure game that plays very much like previous entries in the series. The player sees through Tex's eyes in a 3D environment, moving with the keyboard and using the mouse to point and click at various objects and items. Regularly, a live-action full-motion video cut-scene will be triggered, as Tex (still played by series' creator Chris Jones) interacts with the world and various characters. Aside from series regulars, the game's cast includes several television and movie actors such as Kevin Murphy, Todd Bridges, June Lockhart, Richard Norton, Jodi Russell and Larry Thomas. The game offers several different endings, two difficulty modes, and a built-in hint system.
