As Blue 2 alerts the other Spartans to the presence of the Elites, the trap is sprung. Hordes of Covenant rush the Humans, who quickly fall back into a corner. As Blue Team prepares to make its last stand, they radio Delta Base for reinforcements, only to learn that Delta Base is itself under attack by a massive Covenant army. After a long bombardment, the Spartans at Delta Base retaliate with a volley of rockets and prepare to defend the base.
