The Ratchet and Clank HD Collection
release of August 28 is fast-approaching, so Insomniac has updated their blog with concept art from the early years of the series up to the current aesthetic.

The varied, foreign worlds that have become the environments of the story still maintain an exotic, alien style also.
The image below is what the robotic sidekick was first imagined as. For more of the concept art of one of today's favorite platformers, visit the Insomniac blog here
