Everything you can do out there

A complete list, without the adjectives.

Taking fish

The rod: A tension gauge with a sweet spot, counters for runs, jumps and dives, a power meter that ends in a heave, combos that pay a skill bonus. Rod, reel, line and bait decide how big and how rare a fish you can stop.
Spears and guns: 14 weapons in 10 classes: spears, speargun, pistol, shotguns, rifle, SMG, sniper, launcher, net gun, shock lance. Each can be upgraded to +10 with materials that elites and bosses drop.
Bombs: Dynamite and depth charges. Everything in the radius, at the worst price. A blast near a boat throws its riders in the water.
Trick shots: Headshot, Long Shot, Out of the Air, Double, Clean Sweep, On the Move, Critical, One Shot, Opening, Together, Set Up. Each pays a bonus the moment it happens.
Toss and shoot: Throw a fish from your creel, or have a friend throw it, and hit it before it lands. The further, the better the multiplier.

Wreck Cove: A small island off the pier, by ferry or by boat: a lagoon, an old stone beacon and a timber ship wrecked across the reef.
Diving: Breath runs out fast. A Diving Mask (level 3) gives you more, an Oxygen Tank (level 15) a lot more, refilled at the shops and the cove jetty.
Chests: Seven in and around the wreck, each on its own timer for every player. The ones inside the hull pay best. Morays guard the holes.
Spearfishing: A big fish on the spear line runs and rests, with tension and stamina like a rod fight. The reef is stocked by depth, and a reef shark patrols it.
Swim time trial: A loop through the lagoon, under the wreck's stern and round six marks, against a ghost of your best. Swimmers have their own leaderboard.

Eight sea areas: Crescent Harbour, the Island Shallows, North Creek Mouth, West Reef, Lighthouse Point, and by boat: Coral Islet, the Open Sea and the Storm Sea.
The Storm Sea: Off the west shore, never clear. A ring of light warns of each lightning strike just before it hits, and it hurts anyone standing under it, in the water or in a boat. Meant for level 35 and up.
Day, night and weather: A 24-minute day in four phases, and five weathers: clear, cloudy, rain, storm, fog. Both change what is in the water.
20 fish, 13 other creatures: Five rarities, elites, shiny variants, and fish graded one to five stars by size. Crabs, squid, morays, rays, sharks and octopus. Two animals are protected: kill one and you pay a fine.
24 villagers: Anglers, hunters, boatmen, keepers, kids and a night watchman. They keep hours, fish beside you and fill arena seats when a match is short.
One shared world: Everyone is on the same island. You see other players walk, cast, fight and miss.

Ten world bosses: Six great fish, a giant stingray, a giant octopus, a hammerhead with an escort and Stormcaller, the eel that only rises in the Storm Sea. Each needs its own time of day and weather; the fish also want the right bait.
Three tiers: Normal, Elite and Legendary. Beating a tier unlocks the next. Legendary is built for a party of three or more: alone it is long and it hurts.
Readable fights: Three to five named moves each, all announced before they land. Under 30% health the move set changes and speeds up.
Shared rewards: One health bar, up to eight attackers, rewards by contribution. Landing one earns a title and unlocks trophy clothing.

Three hulls: The Skiff, the Fishing Launch (level 20, a fish hold and four rod holders) and the Sportfisher (level 50, the fastest, with a fish finder and eight rod holders).
The boatyard: At the pier head: turn each hull round, see what it does, buy it and choose which one goes in the water.
Range: The skiff keeps inshore, the launch reaches Wreck Cove and beyond, the Sportfisher goes anywhere. Past its range a hull slows and the sea pushes it home.
Boat time trial: Through the gate at Wreck Cove, round ten buoys in order, back through the gate. A ghost of your best lap sails with you, and every hull has its own leaderboard.

Three grounds: Stag Island and Crag Ridge by ferry or boat, and the marsh at North Creek on foot. Deer, turkeys, goats, sheep, ducks and crocodiles.
The high seat: A ladder up to a railed platform over the meadow on Stag Island. Animals see you less from up there.
Elite and legendary game: Elites are bigger, twice as tough and leave a keepsake trophy. The Croc King, the White Stag and the Goat King are rare, announced, and each gives a title.
Hunter rank: From Novice Hunter to Legendary Hunter.
Staying alive: Out in the wild you only mend slowly. Bandages and first-aid kits heal fast; dishes cooked at a campfire heal and keep you fed.

The Yard: Team Deathmatch: 4v4 on the container wharf. Five minutes or thirty kills. Everyone carries the same carbine; a free rack lets you switch.
The Yard: Cut the Line: Co-op for one to four against flying and running machines. Three relays to cut, a wave for each, an escape, a rating from zero to five stars.
The Yard: Raid: 4v4, first to seven rounds, sides swap after six. One life a round. A buy phase with match-only cash for guns, armour and dynamite.
Open-water PvP: Strictly opt-in. Two players fight only if both fly the fighting flag. Flag up: +15% on fish. Go down: you drop a crate. Kill streaks put a bounty on you.
Poachers: A hostile crew around the far islet and the deep water. They take cover, they retreat, and they pay a bounty.
Duels: Three minutes, a stake each, heaviest fish caught alive wins.

Shared boats: A skiff seats four. Passengers need no licence and can fish and shoot from their seats.
Parties: Up to four, with an XP bonus for staying close and shared boss rewards.
Guilds: Up to thirty members, weekly goals, guild levels that unlock looks.
Friends and messages: Friend codes, name search, private messages, world, nearby and guild chat, a block list. Voice chat with friends and party members.
Trading: A player market with listings and a fee, and face-to-face trades with a lock-and-confirm step; coins handed over pay a 10% trade tax.
Co-op contracts: Daily and weekly jobs for a party: bring down a lord, hunt elite game, land a haul. Everyone has to pitch in, and a bigger party pays more.
Find a group: Post what you are after; others join your party with one tap.
Invite a friend: Share your code. When your friend reaches level 10, you both get coins.

Wardrobe: 100 pieces: tops, bottoms, shoes, hats, glasses, layers, gloves, back pieces, full outfits and hairstyles, with prints and second colours. Looks only.
Character creator: Make the person first: body, face, build, skin, hair.
Aquarium: Only fish you caught alive can go in.
Seasons and quests: Four-week seasons with thirty tiers, daily requests, three weekly quests, a seven-day login cycle that does not reset if you miss a day.
Paragon levels: Past level 50 your XP keeps counting into Paragon levels, with no top: coins, titles and a name colour, never stats.
Events and tournaments: A world event every ninety minutes: Flood Tide, Frenzy Festival, A Lord Rises, Show-Off Hour, Poachers' Camp. A tournament every half hour.
