Before they were legends in the Halo universe, they were soldiers on the front lines. Alpha Corvi II is under a full-scale attack by humanity's newfound enemy, the Covenant. While most of the UNSC's forces have been ordered to defend the colony's primary city, a Covenant strike team has infiltrated a small mining settlement. With resources limited, the UNSC sends the Spartans--the Master Chief and Blue Team--to neutralize the alien threat and discover what they're after. The Spartan strike team quickly finds out that they will have to rely on each other and a small cadre of human rebels in order to survive and complete their mission.

Writer Alex Irvine (Halo: Rise of Atriox, Halo: Tales From Slipspace) and artist Dave Crosland (Halo: Tales From Slipspace) lead us on a thrilling mission from the early days of the three-decade long Covenant War.
