Nice puzzles ruined by a terrible reliance on terrible shooting environments.
The puzzles and platforming are creative (I don't think they're all that new, though). The John Carpenter-like music and the voice acting stand out as the best parts of Rochard. It is unfortunate that the developers didn't stick with adventure theme. If they had ramped up the story, characters, and puzzle/platforming, this would have been a much better game.
One other important thing you should know. Rochard crashed my Slimline PS3 at least five or six times during my playing.
