Squid Operator Hunt is a game where you are a secret operative that was given a mission to infiltrate and stop the Squid game before it starts again. You need to shoot all guards in every location in a given time. Eliminate them all and you'll unlock the next mission. There are some med kits around the map that will help you heal and you can pick up the ammo so you'll have enough to finish the game.
