Jack fires a force-field that can stop monsters dead in their tracks. When angled correctly, the field counters the momentum of a monster with a green beam, quickly depleting its capacity. When not actively stopping the monster, the beam is red and depletes very slowly. It can stop many monster abilities and traversals, and can shove the Kraken towards the ground if angled properly, or even slow a Kraken's divebomb. This allows ample time for your team to escape an Aftershock from above.
