- David, now at the Fourth Frontline Base, senses a massive Zerg Bug Tide approaching. The base's defenses have been bolstered, including upgraded walls and increased Armored Warrior formations.
- David joins Augustine at the defensive line, where they discuss strategies. Augustine reveals that Benton and Garth are among the Armored Warriors, concealing their Transcendent Armor to avoid drawing unnecessary attention from the Zerg.
- David takes up his sniper position, and Lieutenant Mosen delivers sniper bullets for him. The Zerg Bug Tide begins to stir, with a Cyclops Giant Beetle provoking the swarm.
- David snipes the Cyclops Giant Beetle from five thousand meters away, killing it instantly. Babington, the base commander, broadcasts the footage of David's shot to boost morale.
- The enraged Bug Tide surges towards the defensive line. David focuses on eliminating Level 3 Zerg threats. He spots a group of Explosive Jet Bugs gathering energy for a long-range attack, and quickly seals his sniper port with armor plates just in time to block the incoming energy beam.
- The chapter ends with the base's defenses holding strong, and David ready to continue sniping the approaching Zerg.
