Attack of the Clover of Athena City (Cloverfield x Male Spartan Reader)

During the human Covenant war, the UNSC has gotten a distress message coming from the City named Athena City in LunArcadia. The UNSC believed it might be covenant attacking the planet, but they we're mistakened. When they got into the planet, a three hundred feet monster appeared out of nowhere attacking the UNSC fleet.

Y/N, a spartan four trooper was sent down with his teammates to assist the civilians into getting into a transport ship but the Clover swung it's tail into the bridge killing every member Y/N was in. Now alone, Y/N stumbled onto a cop, young boy and two ladies who we're fighting to survive and reaching they're wounded friend who was trapped in her apartment.

What will happen next?
