PK was Crypto's most known mental ability, as it was present in every game to date. PK allowed Crypto to pick up objects with his mind and came with multiple variations over the years. In Destroy All Humans! and Destroy All Humans! 2, Crypto could move it in or out, as well as push it in the direction the object was moving, with the former version slowly draining your Concentration. In Destroy All Humans! Big Willy Unleashed, it was controlled via motion controls, rather than with standard buttons, as Big Willy Unleashed was present on the Nintendo Wii. Destroy All Humans! Path of the Furon's version of PK was very different from the previous incarnations: objects that were affected by PK stayed locked in a set distance from Crypto, but he could fly with his Jetpack while doing so, and could throw it where the crosshair pointed, rather than which direction that the object moved. The new PK also included the ability of PK Magnet: it pulled nearby objects to the one that Crypto lifted, which allowed for multiple objects to be carried at once.
