A group of identical clones all known as "Clyde" work together to try to escape the laboratory in which they are trapped.

The player has the ability to switch between multiple Clyde clones at any time in order to progress/solve increasingly complex puzzles.

As they progress through the level, more Clydes can be found inside crates or created using cloning machines.

This score is dependent on how far under the par time the player completed the level in, and also the number of "Killer Kenn" action figures that were collected.

Both multiplayer modes can be played either online using Xbox Live or locally using split screen.
