About this project

What does Blood Hardcore Survival add?

Blood Hardcore Survival

**A brutal hardcore survival overhaul for Minecraft 1.20.1 (Forge)**

This mod transforms vanilla Minecraft into an unforgiving survival experience with realistic body mechanics, deadly environmental disasters, deep underground exploration, new ores, diseases, and much more.


Features

Survival Stats System

  • **Temperature**: Dynamically changes based on biome, altitude, weather, time of day, and water exposure. Get too cold? Hypothermia. Too hot? Heatstroke.
  • **Thirst**: Stay hydrated or suffer dehydration. Collect rain with Rain Collectors, purify dirty water with the Water Purifier.
  • **Bleeding**: Physical damage has a 2% chance to cause bleeding. Use Bandages to stop it.
  • **Infection**: Zombies can infect you with Blood Plague (25% chance, reduced with Gas Mask). Cure it before it progresses!

8 Dynamic Natural Disasters

Disasters strike randomly and without warning:

  • **Earthquake** - Ground shaking, block disruption, screen shake
  • **Tornado** - Destructive funnel entity that tears through the landscape
  • **Meteor Shower** - Fireballs rain from the sky
  • **Acid Rain** - Corrosive precipitation that damages players and blocks
  • **Blizzard** - Heavy snowfall with freezing cold damage
  • **Heat Wave** - Extreme temperature spikes causing heatstroke
  • **Flood** - Rising water levels and drowning risk
  • **Volcanic Eruption** - Lava bombs and terrain destruction

Extended World Depth (Y = -384)

  • The overworld extends down to Y=-384 (3x deeper than vanilla)
  • Deeper mobs are stronger (scaled health, speed, and damage)
  • Water pressure damages players in deep ocean areas
  • Blocks become harder to mine the deeper you go
  • Void damage triggers at Y=-384 instead of Y=-128

Cancer & Radiation

  • **Uranium Ore** spawns deep underground and glows
  • Standing near uranium causes progressive cancer (Stage I → II → III)
  • Wear a full **Hazmat Suit** for protection
