Odd Engravings are items in killer7. They are found in every single mission except Target06: Lion. Odd Engravings are strange objects typically required to unlock security systems and gain access to new areas. They are found throughout the game, often in unusual locations. Although each Engraving is unique, they are all similar in that they have a silvery-grey, metallic appearance. They are often highly ornate and intricately detailed; conversely, their only purpose is to be slotted into dull, ordinary-looking panels and machines in order to allow the Smiths to access the mechanism inside.
