Declassify Mission: Locusts use Oneshots
Once the section starts, follow your team to the breached door and look on the ground to your immediate left. You should see some bloodstains on the floor with a COG tag.
The declassify mission skull ahead will allow locusts to use Oneshots when activated. Proceed outside and prepare for a locust beach landing.
You may want to position one of the Gnasher sentinels in the opening of the bunker to the left and position another sentinel beside the other mounted turret. Man one of the guns and wait for the locust amphibious craft to arrive. Prioritize taking out the heavy targets such as boomers and kantus priests. Remember that you can also speed up the turrets' cooling by pressing RB.
You may want to also put some frag traps and tripwire arrows behind the covers that the mortar units may use or near the openings where the locusts may enter. To ensure your safety from the mortar rain, defending your position in the left bunker will be a good choice. Survive the next few waves of enemy landings then head to one of the boats to complete the section.
