Addle Earth

Addle Earth is an action, single-player game, that follows the story of three characters, and how they managed to save the world:
Kit - the girl, Che - the ape and Moses - the alien, as they run through a futuristic, abandoned and confused Planet Earth to fight mechanical enemies (machines and droids).

All three characters have their own unique strengths, and players will explore them in individual stages.
However, as they get together in the story, players will then be able to choose and switch between the characters while playing.

The game employs a nonlinear narrative structure​, with the story based
upon its protagonists and their memories as they get interrogated by a federal agent.

Although the character are three-dimensional, the game is presented as two-­dimensional with an isometric camera and a
digitally ­painted, colorful art style.
