When the player encounters a ghost, they must first shoot it to weaken it to a point where it can be captured. Capturing a ghost is accomplishing by hitting it with a "Capture Grenade." If the player uses the grenade before weakening the ghost sufficiently for capture, the grenade attaches itself to the enemy for a limited time, and a health meter appears. If Jones depletes the health meter whilst the grenade is still attached, the monster will be captured. The grenade can also be used to pick up ghost energy and health orbs which the player cannot physically reach.
