Weapons in Brutal Nature are highly realistic, They all fire actual projectiles that take time to reach the target and have drop due to gravity along the way as well as experience air drag that slows them down and reduces impact damage.


Damage depends on mass times velocity squared of the bullet with each weapon having its own muzzle velocity. Bullet and case weights, muzzle velocity, etc are based off real world values. Each weapon also remembers its magazine count and ammo type when you change weapons. Weapons have multiple types of ammo, each with their own bonuses and penalties against armor or lack there of.


Weapons, armor and ammo all add to your encumbrance. encumbrance slows you down and makes you use more endurance to walk.

Your overall health in Brutal Nature is broken down into 3 categories: Health, Food and Endurance.


You die when you hit 0 health. Having no food or endurance is not fatal however low health, food or endurance will make tasks much harder to do. Health is slowly restored using up your food any time your health is not 100%. Low food will slow health regeneration.


Endurance is used by all actions: Moving, firing, reloading weapons, butchering animals, etc. It is regenerated automatically by using up food, or health if there is no food left. As such running out of food will lead to a death by starvation where every action you take makes you starve to death faster. Endurance regeneration slows with low health or food and speeds up when endurance is lower.


Low endurance slows movement rate and decreases ability to control weapon recoil. Most other actions require endurance to execute. This means everything you do uses up food and every action places a demand on your endurance. You feel the effects of low health, endurance or food before they run out. 


You should always try and keep health, food and endurance above 50% in combat. Working harder and lowering endurance further will let you do more but will put you at a disadvantage if you must engage in combat.

Crafting is kept simple to do with a menu of recipes to guide you through the very detailed crafting tree of over 700 recipes. Select a recipe and it will show you its ingredients, how many of each ingredient you have, how many you can make and the recipe's output. You can then just type in how many you want and click craft. Nearly every item has flavor text explaining where you make it and what it is good for.


Terrain is mined in Brutal Nature to provide ores and building materials. Objects like trees can be harvested for wood. Using materials you can make buildings like smelters and camp fire to further craft objects. You can also craft light sources to light up your mines and houses.

Each building has a limit on the quantity it can craft at once and crafting takes a set amount of real world time before it completes. Most buildings also require fuel (Coal, wood, etc) to craft an item. Most buildings have visible effects to indicate when they are in use.


Chemistry is a part of game play with realistic recipes to make everything from everyday items like glass and steel alloys to explosives like TNT and Gunpowder. Very accurate chemistry recipes are used in the game that loosely follow the real world methods to make things.


Ores can be smelted by using coal, coke or charcoal into metals at the smelter. Some ores require chemistry to refine. Metals can be used to produce armor, weapons and ammo. Some recipes require higher quality fuels while others can use any fuel.


Electricity is implemented. You can craft generators, junction boxes, electric lights and electric smelters then wire them all togethor. Each load has a different power draw and each generator has its own power limit. Generators draw additional fuel when under higher load and different generators have different fuel efficiency levels. Batteries can be used to store electrical power and switches can be used to turn parts of your electrical grid on/off.


Dead animals can be butchered for meat and skinned for hide. meat can be eaten raw or cooked into different meals while hide can be used to make armor and clothing. Food can be cooked into different dishes depending on what ingredients you have.

  • Fully editable terrain. Dig down thousands of feet below the ground and build just as high above it.
  • Smoothed and cube voxel support.
  • Cubed voxels support arbitrary sizes and can be exceptionally small.
  • Destructible terrain, blow terrain up with explosives, damage the terrain with bullets. Supports very large and rapid explosions with ease.
  • Destructible plant life and world objects, everything can be destroyed.
  • Supports tens of thousands individually destructible and harvestable trees and other flora.
  • Miles of caves to explore.
  • Terrain editing preview.
  • Terrain Generated from erosion simulation of user provided heightmaps allowing for realistic terrain and detailed modeling of sediment deposits, rivers and lakes.
  • Shadow mapped terrain supporting self shadow.
  • Can restrict editing along the X/Y/Z axis for ease of making walls, floors and ceilings.
  • Easy to use adjustable grid size editing system.
  • Water Physics: Water flows down hills until a set slope is reached. Water can be picked up and moved.

Terrain in Brutal Nature is voxel based converted to a smooth mesh. It can be destroyed by weapons fire, mined for resources and placed to construct structures. It can be mined or placed up to thousands of feet in every direction, tunnels and bridges can be made as it is a true voxel data structure.


It is initially generated by taking a user provided height map, running it through a fluid erosion simulator and then exporting it as a custom format. This allows any terrain to be easily imported into the game. Once generated, regions are assigned on a 2d basis and sub-regions within those on a 3d basis, different sub-regions having different soils, stones and ores, this provides a level of order by location while allowing variation based on depth and biome.

The Brutal Nature team currently consists of just one full time programmer and a few artists who contribute now and then.



Black Moon:

I started this game because I wanted a survival sandbox game that natively supported mods and complex game play. I work full time on Brutal Nature and there is nothing else I would rather be doing. I am talented in C++ programming, machining and electronics. I hope to bring my knowledge of the world into Brutal Nature to make it a highly realistic game where you can create anything in a believable manner.
