Fathomcraft

Fathomcraft is a Minecraft Fabric mod for version 1.21.1. It is made for an immersive horror episode that is coming soon. This mod takes inspiration from the looks of "Bodycam" and "Fears to Fathom".

Main Features

  • Bodycam. Vhs Filter: When you play you will see an overlay on your screen that looks like a real body camera. It shows the date and time and it even looks like a video tape. This effect is always on when you are in Survival mode.

  • Dynamic Flashlight: You can turn on a flashlight by pressing the F key. It does not just turn on and off it also flickers a bit like a real flashlight would. This makes the game feel more scary and real.

  • Immersion & Movement:

  • Camera Inertia: When you move your head it feels like it has some weight to it. This makes the game feel more real.

  • Weapon Sway: When you are holding something it moves a bit in your hand. This is because the game is trying to make it feel like you are really holding something.

  • You will not hear the sounds of your feet moving. This is so that the game can use its sounds to make it feel more real.

  • Realistic Inventory (Survival): When you are playing in Survival mode you can only carry a things at a time. You can only use two slots in your inventory. You cannot pick up anything else if your hands are already full. The game also hides your health and hunger meters. Instead shows you a simple inventory bar that you can see when you need it.

  • Narrative System:

  • The game has a way of making characters talk to you. It looks like they are typing out what they want to say.

  • There are triggers in the game that can make things happen when you walk through them. You can see these triggers if you use an item called the Trigger Remover.

  • Entity Censor: When you see guys in the game they are covered up by a black box. This makes the game feel like you are watching a video tape.

  • New Decorative Blocks: The game has blocks that you can use to build things. These blocks look like they are from a city and they can help you make your world feel more real.
