Recently, the popular action online game "Sealer" released the latest professional promotional film, this time bringing a real demonstration of Kim Chul-so's five-turn "Shadow Agent".
Kim Chul-so is a new member of the Brown Rats, but he is already very experienced when he joins the team, and his gorgeous gun fighting skills make the squad members respect him very much. But he has already lost his memory due to an accident when he joined the team, and only the cold killer instinct has been preserved, so he will gradually retrieve the truth of the lost memory.
