A game that is marketed as your standard fishing game and for the first 20 minutes or so you catch normal fish like bluegill and bass and what have you. But the further you go into the lake you start to catch fish with mutations and it gets more and more intense until you’re pulling in Eldritch horror monsters and sometimes severed human limbs. You realize you don’t recall how you got to this lake in the first place and the objective becomes to find your way back to shore. You have no real weapons but you can throw the creatures you’ve caught far away from the boat as a means to distract whatever is underneath you, bumping into the boat sometimes. Additional items for the game.

A fishing pole with a radar that starts out with just beeps but later includes noises with hidden messages.

A GPS that displays texts and story elements.

You meet other boaters, all from various backgrounds, countries, and time periods. Some are friendly, others want to sacrifice you to the lake monsters.

You can also take the route of sacrificing others to the lake monster.

Or you can assemble a party and work to keep them safe.

The more fucked up looking the fish you catch, the closer you’re getting to a boss fight, which is usually running from something you can only see part of in the water.

It never stops being a fishing game. You are always fishing and searching for new areas where there is more activity in order to progress the story.

Depending on the choices you make and the amount of mutant fish you consume, you may start to mutate yourself. The fishing pole is part of your arm, you don’t notice it until later. If you consume mostly non-mutated fish and don’t sacrifice to the monsters you can keep the mutations to a minimum.

You can go full mutant and the boat becomes part of your body as well. This makes the monsters pay less attention to you, but you can no longer befriend or trade items with humans. You can still catch human remains and most of them are carrying items.

If you stay mostly human you can work to gather as many surviving humans as you find and assemble a fleet. The possibility of one of them turning on you always stands.

If you’re mutant you gain the ability to capsize yourself and view things under water. This is how you find ultimate monster.

If you’re human you can explore small abandoned docks and islands. These are where you find portals leading to different time periods and countries. You deliver members of your party to these. Only the person who originally belongs there can go through it.

Possible end game situations.

You find the portal leading back to your world, where you wake up on the river bank. You can catch normal fish before going home, making sure they are all free of mutations (they might not be.)

You join the monster, eventually overtaking it. You gain the ability to open time portals near water. You use lures to draw in humans.
