Playing from a third-person perspective, you move Wallis around by clicking the arrow in the direction in which you'd like her to travel. If an object can be interacted with, the mouse cursor will change to a magnifying glass for further inspection. Puzzles she faces might include picking a lock, solving a Rubik's Cube, reinstating power at a facility to hack into a security program, or following a recipe to make glue in order to patch a hole in the wall. At times you'll be asked to combine items in your inventory to create something new. When you meet characters you can talk to, you'll be able to select questions or responses from a list of branching conversation paths, which can affect the outcome of the story.

Culpa Innata offers a deep and immersive experience that rewards players for unraveling a complex story, interacting with interesting characters, and solving intelligent puzzles. The game might not single-handedly resurrect the ailing PC adventure genre, but it should serve as a reminder that these once-popular games are still alive and well.
