Ghost, Gaz, Soap and Price were all pirates and Price was obviously the captain… and they were looking for other pirate ships to raid and steal their treasure until they saw something in the distance it was another pirate ship but it was getting attacked by a sea monster(specifically a big ass kraken)

Ghost: “Holy shit… that’s the biggest kraken I’ve ever seen…”

Price: “we will not go over that way… we aren’t strong enough to kill the kraken”
