With Earth forces evacuating the Fissure, the Office of Naval Intelligence primed the nuclear devices, and made a final call for any remaining forces to evacuate as quickly as possible. With the final UAC forces making the dash to exit the area, the nukes are detonated, the strategically placed devices went up in a massive nuclear fireball, eradicating any remaining information and any military forces within their general vicinity,and radiating the areas nearby it.

The UAC fleet in orbit makes a fallback 100,000km from the gravity well, and began to activate their engines to move closer to the Tenelapis moons. An encrypted and untraceable transmission is sent UACHIGHCOM, which then relays it to Vice Admiral James Zahn, giving orders to dispatch two UAC fleets, one to reinforce the main fleet, and another to head to Vent Gamma to defend it, with the authorization to use any means necessary to defend it.
