Big and Small – Genes & More Mod

Author of the Big and Small – Genes & More Mod: RedMattis

Biotech Genes and Traits Framework Mod is a core mod that includes a number of Biotech genes, traits, and the C# framework necessary for other mods to work. In total, the mod contains 68 genes (as of writing), 11 of which are related to size. All are balanced for vanilla. If you feel anything is “OP”, please send your feedback and I’ll look into it.

This mod was originally part of the Big and Small Races Mod but was split into its own mod so that you don’t have to deal with Jotun if you just wanted small goblins, big space marines, or whatever suits your fancy. If you want the mod that makes use of the genes included here, see the Big and Small Races mod.

Big and Small Races

Genes (150+)

This is just a sample of genes from the mod. As of writing, the mod has 150+ genes. Many of the genes do not spawn in genepacks and are found only on specific xenohumans. This is often the case with purely cosmetic genes to avoid bloating genepacks.

(Note: The graphic below is old. Most genes have new art, and a variety of new interesting genes have been added since.)



Beyond game-play affecting genes like the above, there is also a number of cosmetic genes such as horns, skin & hair colors, etc. Most of these are either rare or simply will not spawn in genepacks to avoid bloating your chances of finding things you actually want.

Body Size Details

Size Offset
The offset genes will increase or decrease the size of a pawn by a certain value. For obvious reasons, there is a limit to how small a pawn can get. This could be considered the primary way in which a pawn’s size is changed.

Size Multiplier
These genes will multiply the pawn by a certain value. This stacks with the Offset genes, meaning you can have a Jotun-frame pawn with dwarfism, or a Dwarf-frame pawn with gigantism. This will also work as you’d expect with pawns which have a base size smaller or larger than the 1.0 of humans.

Traits
There are traits working identically with the Size Multiplier Genes mentioned above. If a size-multiplier gene is present on a pawn with such a trait, it will override the trait.

Size Matters

  • Dramatic effect on max nutrition.
  • Very large effect on nutrition use.
  • Alters Body Size attribute and associated traits.
  • Dramatically modifies health.
  • Alters damage, a bit less than the linear increase.
  • Large effect on Melee Dodge chance benefiting small characters.
  • Very large effect on Self-“Production” from Alpha Genes and Biotech Expansion genes.

Minimizing and Giantizing Animals

Animals can now also be shrunken down or enlarged. Shrunken animals retain a decent amount of their previous sturdiness, become faster and more evasive, but are less capable of dishing out pain. They also eat less. Enlarged animals are bigger, sturdier, better at dishing out pain, but slower and hungrier. Giantizing small animals has the most dramatic effect.

Gene Tools


All 5 gene tools are craftable at the Drug Lab.

Weapons

Adds a few giant weapons that can only be wielded by Giant pawns, Herculean pawn (Roo’s Minotaurs), or Warcaskets.

Giant hammer, giant club, giant warhammer, jotun longsword, Skrýmir’s Mallet, Sword of Surtr.

Throwing boulders, jotun javelin, warmech anti-material rifle, and warmech minigun and rocket launcher.

Meals

When using this mod your pawns will also grab multiple meals if it would be required to fill their hunger bar.

The mod added Large variants of most vanilla meals to make feeding large pawns easier before they could grab multiple meals. They are a bit redundant now that pawns can grab several meals but it is left in as legacy to avoid breaking people’s saves.

Compatibility notes

If you are using [VL] Facial Animations with HAR, you may need to turn off the ‘Experimental Beard Misalignment Fix’ if you get misaligned beards.

Mod Interactions

  • Vanilla Weapons Expanded – Heavy Weapons – Giant pawns (Jotun/Ogre frame and up) can use Heavy weapons without Tough or Exoskeletons.
  • Roo’s Minotaur Xenotype – Giant pawns can use the big minotaur weapons, they are also patched to behave as if “Herculean” for the purpose of the mod’s, uh, “crushed pelvis” mechanic. Ow.
  • Vanilla Factions Expanded: Pirates – Giant pawns can use Warcasket weapons.
  • Vanilla Races Expanded – Android – Adds a number of genes to your Android crafting menu, including the most notable size-genes.
  • MH: Android Tiers Core – Adds several frames so you can make big and small androids or biometric units.
  • Universum/RimNauts & Save our Ship 2 – Adds genes which lets pawns handle the vacuum of space.
  • Zombieland – Depending on genes some pawns will not be infected or rise as zombies. Ghouls & Returned have a gene which makes zombies ignore them.
  • CE – Fully compatible with the Character Editor.
  • And Combat Extended. Patched by them, not by me. :)

Recommended Mods & DLC

Vanilla Genes Rebalanced – The Xenotypes in my other mods are built assuming that you have this.
Better Gene Inheritance – Makes children of xenohumans not be 7-gene 225% disappointments.

Anomaly

Humanoid Alien Races – Required if you e.g. want snake tail to actually give the character a snake tail instead of legs, etc. Otherwise, the change won’t be reflected on the health tab and a number of HAR-only genes won’t be available in your game.

Known Issues

None known. Contrary to claims, Outland Genetics is not incompatible with this mod. You can safely use them together. Let me know if this changes.
