This isn't the first time a special COG unit has been dispatched with the goal of deploying a resonator-like device in the Imulsion mines. Unfortunately, that previous team was unmercifully slaughtered by the Locust Horde and direct access to the mine has been sealed off ever since. No, this time things are going to be much different. Not only must Delta Squad search for an alternative entrance through the Lethia Imulsion Facility, but they must be sure to get in and get out before sunrise. After all, with so few humans left to feed upon, the Kryll may still be hungry when they return.
