M. Macaulay was a member of the United States Colonial Marine Corps from the USS Sephora. He was involved in a search and rescue mission sent to LV-426 aboard the USS Sephora in 2179 to investigate the disappearance of the USS Sulaco and its crew 17 weeks earlier.

Macaulay was killed when his team was ambushed by a pack of Xenomorphs on board the Sulaco.

On the Sephora

Macaulay was stationed on the USS Sephora in October 2179, which was sent to investigate the rediscovered USS Sulaco above LV-426.

On the Sulaco

After boarding the Sulaco, Macaulay and his team discovered too late that a Xenomorph infestation had broken out on board the station. After several run-ins with the creatures, the men had expended most of their ammunition.

Eventually another pack of Xenomorphs attacked Macaulay's squad, capturing or killing the entire team in short order owing to their lack of remaining ammunition. Macaulay himself managed to escape in the chaos and hid amongst debris.


Macaulay's luck would soon run out when he was found by the Xenomorphs. With no ammunition to defend himself, he was quickly captured or killed by the creatures.
