There are boatloads of Landmarks and Quests that players can find, many of which that also double as Easter Eggs that contain shout-outs to other video games, TV shows, movies, etc.
- Some of the higher-level shark-hunters will throw pressurized scuba tanks into the water and blow them up — one of the game's many references to Jaws.
- You can find the "Sea Sponge Home", which just so happens to be a pineapple under the sea.
- There's an island with "HELP" written on the beach with stones and a volleyball, which the narrator quips are better friends than backstabbing soccer balls — a reference to Cast Away.
- There's three giant seashells. The fact that finding them gets you the words "You're Out of TP", alongside the narrator making the reference more blatant, is a reference to Demolition Man's infamous Three Sea Shells.Narrator: In the not-so-distant future, a young visionary entrepreneur will spot these three shells while snorkeling and revolutionize after-toilet care.
- One of the Landmarks, called "Saviors", happens to be a strange mural of stone carved to look like the default playable cast of Killing Floor 2. The narrator even outright calls it an opportunity for "cross-franchising".
- Speaking of the Killing Floor Franchise, one of the Landmarks just so happens to be a sunken and broken logo of Horzine. One can even see said logo intact on one of the skyscrapers out in the distance. Horzine is also mentioned in the bios of one of the elite shark hunters, who send him to recover the shark's corpse so they can weaponize it.
- A pig's head on a stick can be found on a hidden beach, with the narrator snarking that someone should've done their 6th-grade reading assignment and the associated achievement for finding it being "Kill the Pig".
- In one of the sewers is a Landmark of a clown holding a red balloon, titled "Down Here We All Float", in a reference to It. The narrator makes a remark about the rise in clown-related homicide to boot.
- Upon finding the sunken UFO, the narrator makes a reference to the planet Gazorpazorp from Rick and Morty. Which is fitting considering whom is voicing the narrator.
- One of the landmarks is an underwater base from The Spy Who Loved Me as the narrator makes a reference to Ernst Blofeld.
- A chained door with an engraving of Cthulhu's face can be found at the bottom of the ocean, with the narrator making a reference to the Rift from Pacific Rim.
- A taxidermied giant crocodile with a clock in its mouth can be found in the swamp, a reference to Peter Pan — in particular Hook, where the crocodile that ate Captain Hook's hand was killed, stuffed, and turned into a makeshift clocktower.
- One of the bayou's Landmark names is a reference to Ian Malcolm's panicked "Must go faster! Must go faster!" line from Jurassic Park.
- One of the landmarks is a humanoid figure made out of tires as a reference to Bibendum, the mascot of the Michelin tire company. Discovering it earns the "Legally Distinct Tire Man" trophy.
- The trophy about the legality of using hockey sticks to play golf being contested by a man named Doug Thompson is a reference to Happy Gilmore.
- One of the Landmarks is a billboard depicting a cartoon tiger cereal mascot... with a car rammed into it — a parody of Tony the Tiger, mascot of Kelloggs' Frosted Flakes. The name of the Landmark and the licence plate on said car are references to Tiger Woods, fitting as the Landmark is found in Port Clovis' golf park.
- Harsher in Hindsight following Tiger Woods' vehicular accident in February of 2021 (the game was first released May of 2020).
- One of Sapphire Bay's Landmarks is a sunken frozen banana stand, the title of which is a reference to Arrested Development.
- A replica of the Titanic can be found in the Gulf, with two skeletons posed at the bow like in the Titanic movie.
- The name of the "Point Broken" Landmark is a reference to the Point Break movie.
- "Oh, Sean's Eleven" is a pun on Ocean's Eleven, with the Landmark itself being the result of a casino heist gone horribly wrong.
- The Apex Sperm Whale boss is an albino studded with harpoons — much like Moby-Dick.
- There are a couple of Cthulhoid statues hidden in the game world, and Captain Robert Brunlett is a veteran of the Battle of Innsmouth; though the narrator remarks that the eldritch gods of yore do not enjoy being summoned to Port Clovis — all references to the Cthulhu Mythos.Narrator: If a group of consenting adults wants to perform cryptic rites to shadow forth the prophecy of the Great Old Ones... heh, who am I to judge?
- Mahana the Apex Killer Whale has a bent dorsal fin, a common condition for orcas in captivity, as seen in the iconic docudrama Black Fish and film Free Willy. The name of the mission to kill Mahana is Killer Queen.
- One of the Gulf Landmarks is a sunken patchwork Trimaran that the narrator said sunk while looking for The Mythical Dryland.
- The mission to take down the Fawtick Bayou Apex Predator, Rosie the alligator, is called "Whole Lotta Rosie".
- One landmark in Sapphire Bay is the site of a "Fyah Fiesta", referring to the infamous Fyre Festival concert in the Bahamas. The narrator has a laugh at the people who shelled out thousands to be dumped onto a deserted island to listen to Swedish DJs.
- One of Trip's quips should the Maneater win against an alligator is that the success of the film Megashark Versus Gatorsaurus — a pastiche of the The Asylum giant monster movie Mega Shark Versus Crocosaurus — has spurred an increase in the popularity of shark vs. crocodilian battles.
- The title of the mission where the Maneater fights the Apex Sperm Whale is "Whale Hello There!", a nod to Obi-Wan Kenobi's memetic line in Revenge of the Sith.
- The congratulatory screen after finishing the main story is "JAWSOME!" — the catch-phrase of the Street Sharks.
- In "Truth Quest" one of the landmarks is "Flickerdelphia" — a glitchy World War II ship stuck in an interdimensional portal, which is a reference to The Philadelphia Experiment.
- The Atomic Set grants the shark armored black scutes, jagged dorsal spines, and a Breath Weapon — also possessed by the DLC's final boss, the Atomic Leviathan — in reference to Godzilla.
