You are in the middle of a warzone under attack, outnumbered by a ruthless enemy. They are chipping away at your health, take them down before they take you down. 

Mind the connection between the Alphas and the Drones. Taking down an Alpha enemy reduces the hitpoints of the Drone army for 1 minute. Take advantage of this to help clear the battlefield. 

The pyramid has a hidden passageway taking you to a chamber into the upper level of the structure where more enemies are hidden. Good luck in your fight!
