Search haunted buildings for paranormal entities known as ectomorphs. Once you spot an ectomorph, aim your device at it, and then click and hold your left mouse button until the extraction process is complete. Releasing the mouse button too soon or too late will result in a dead ectomorph. Your objective is to capture as many ectomorphs as possible before sunrise. If you capture enough ectomorphs, you will be able to upgrade the device that you use to capture them.
