This mission has players playing on the Drone multiplayer map. We need to defend three objective markers from an almost endless supply of enemies for 10 minutes.
As long as you defend two of the objective points, the enemies will not be able to enter your main base and destroy it. If they are able to destroy two of the three objectives outside, a fourth point - Objective D will appear. In this instance immediately order all of your forces to defend point D.
As you have limited resources and the enemy forces are numerous, my strategy was to send one group of infantry to Objective C to slow down the enemy advance there, whilst using the second group of infantry on the helipad at Objective A and using the turret here when necessary to defend the street below from enemy forces and hover drones coming from Objective C. Allow the CLAW to defend Objective B.
When re-enforcements arrive, use them to boost numbers at both point A and B and if you feel a little adventurous, send another infantry unit down to Objective C to help slow any enemyies advancing towards the other two objectives from here.
Once your numbers increase at the A and B objectives, use tactical view to help your units target incoming enemy attacks and if you lose one of your final two defensive objectives, immediately send all your troops to Objective D and hold out until the end of the level.
Once the timer is up, you will complete the mission.
Successfully defend FOB Spectre from incursion.
