Includes Damon Baird, Marcus Fenix, Dominic Santiago and Theron Guard.

Damon Baird is ruthless in battle and regularly decorated and promoted for his tactical genius. Unfortunately, he is then demoted for his frequent bouts of insubordination and bat attitude. His intellect and engineering skills come in handy for battlefield repairs or understanding Locust strategy. After years of fighting, his only remaining motivation is self-preservation. He'll do whatever it takes to get through the war alive - even march alongside a troublemaker like Fenix.

Marcus Fenix established himself as a war hero during the Pendulum Wars. He was on the fast track to an outstanding military career - until the monstrous Locust Horde emerged from the underground. Now leading the Delta Squad, he simply fights for survival.

Dominic "Dom" Santiago and Marcus Fenix have fought side by side since the Pendulum Wars. It was Dom's unwavering loyalty and friendship that saved Marcus' life before the military tribunal, and again when he pulled Marcus from a Locust overrun prison into Delta Squad. Dom's two children were killed on E-Day, and his wife was lost soon afterwards, so his fight against the Horde is deeply personal.

Theron Guards, the Queen's elite shock troops, demonstrate greater intelligence, strength and speed than average Locust Drones. They communicate their orders in hissing whispers that carry on the wind, bolstering faraway allies and sapping enemy morale. The Theron's torque bow fires explosive quarrels with a delayed timer, leaving just enough time to savor the enemy's fear before they explode in a fountain of blood.
