In the 'Old boys club' mission you will have to deal with the Hiss monster that is absorbing matter in Parapsychology and preventing you from reaching your destination. This beast is locked in a separate room but to continue the mission you will need to open the passage to it. The problem with this beast is that it cannot be killed, throwing objects at it with Jesse's telekinesis will only stun it for a moment. This How to solve the Parapsychology Puzzle in the Old Boy's Club mission will show you how you can safely lock it away so you can continue with the mission to find Marshall.
To begin with you need to open the door and continue along the tunnel until you reach the room where the monster is. You will enter this room on the right and you should see two orange, electricity boxes. Pick these up using Jesse's telekinesis and place them on the two sockets either side of the large door. While you are doing this you will need to keep an eye on the monster as it will be slowly moving towards you. Once the batteries are in place return to the door at the entrance of the tunnel you came down and wait for the approaching creature. Let the creature approach you, then go through the door and quickly run to the control panel and press the button. You have to be fast as you do not want to let the monster get out of the tunnel. If you were quick enough the creature will be trapped and you will be able to continue your search for Marshall.
