While on a reconnaissance mission, the team was ambushed and one member was killed, which made the situation even more tense. Since then, they have clashed with the enemy many times, and each battle has been terrifying. Not only are the enemies familiar with the environment and well-armed, they also have terrifying tactics such as mysterious monsters.

During the battles, the team constantly found themselves in desperate situations, only to be saved at the last minute. They received support only to be surrounded again; they attempted to break out only to encounter new crises. But they never gave up. With unwavering faith and indomitable perseverance, they fought the enemy to the death in the streets, parks, warehouses and other places, constantly seeking the truth about the terrorist organisation and striving to safeguard the peace of Europe.
