Gunlok Interview on RPG Vault is a talk with developers Rebellion on the storyline and features of their upcoming futuristic action RPG. Here is a quote on the basic concept of the game:

Corporate rivalry reached a peak in the mid-21st Century and exploded into decades of war and human persecution. Now cyborgs, more robot than human, rule the planet and their corporations are systematically exploiting its remaining natural resources. Original humans have all but vanished. At an industrial complex a robot is changed forever by an energy anomaly that triggers consciousness in his robotic brain. This is Gunlok, the first robot to dream. With his new thoughts comes the power to trigger consciousness in other robots and the power to tap into a 'magical' energy field of 'Earth Power' that surrounds the Earth. Gunlok sets off on a quest to discover his origin. On this quest he will uncover the fate of the original humans, lead a fight against the tyrannical corporations and release his robotic brothers from bondage. Finally he will confront his arch nemesis, the demonic cyborg Skorn.
