In a Hydra corridor, Dum Dum Dugan wields a stolen energy weapon, vaporizing several Hydra soldiers as he, Gabe Jones, and Falsworth press forward.

At the base’s entrance, Peggy Carter and Allied forces storm the motor pool. Hydra troops retreat toward the complex, their energy weapons disintegrating several Allies, but their numbers dwindle rapidly under the onslaught.

In another corridor, the Red Skull glimpses Allied soldiers breaching an entrance. He snatches an energy weapon, fires a barrage at the advancing troops, and flees deeper into the complex. A small squad of Hydra soldiers charges the Allies in a narrow hallway, only to be cut down by a hail of bullets.

One zealous Hydra soldier, mid-charge, shouts, “Cut off one head, two more shall…” A gunshot from Colonel Phillips drops him mid-sentence. “Let’s go find two more!” Phillips barks, rallying his men.

Steve Rogers pursues the Red Skull closely, deflecting energy bolts with his vibranium shield. The Red Skull ducks behind two closing metal doors, but Steve hurls his shield, which ricochets off a wall and lodges between the doors, jamming them open.

A Hydra soldier with twin flamethrowers blocks Steve’s path, unleashing torrents of flame down the corridor. Steve dives into a vestibule, narrowly avoiding the scorching blaze. The flamethrower advances, but Peggy Carter appears, machine gun in hand, and guns the soldier down.
