Yayo’s Combat 3 Mod

Yayo’s Combat 3 Mod is an updated version of YAYO’s Mod, based on the abandoned 1.3 update by Ogliss. It completely overhauls RimWorld’s combat system with new mechanics, realistic armor penetration, ammunition management, and improved AI combat logic.

Yayo’s Combat 3 Mod Features

Completely changes the combat system.

Powerful armor algorithm

Penetration becomes a crucial factor in combat.
High-tech armor can no longer be pierced by low-tech weapons.

Ammunition system and loadout

All ranged weapons consume ammunition.
When enemies run out of ammo, they switch to melee combat with their guns.

Ammunition is categorized by tech level and damage type.
For example, flamethrowers require industrial explosive ammunition.

You can configure ammo and medicine loadouts under the drug policy tab.

Other features

• Realistic accuracy algorithm.
• Increased projectile speed for stunning effects.
• Fixed armor coverage to protect hands or feet (when protecting arms or legs).
• Options menu to control all these systems.

There’s no need to use it with other Yayo combat versions; the latest version always includes the features of the previous ones.

The accuracy algorithm now correlates more closely with shooting skill, eliminating the unrealistic “shooting rabbits all day” problem.

The armor algorithm compares the weapon and armor tech levels to calculate penetration power.
If the armor is superior, it deflects almost all attacks.
If the weapon’s penetration is high, it quickly reduces armor durability.
Once durability drops below a threshold, bullets start to penetrate.

Durability thresholds are determined by comparing penetration and defense values.
Strategy tip: reduce enemy armor durability first with high-tech, high-penetration weapons before switching to standard fire.

Compatibility notes

Tutorial for modders: set custom ammo for weapon.

Changes from 1.5

The advanced animations have been removed.
If you want those animations, add Yayo’s Animation, which provides the same visuals.

• Fixed the missing config-text.
• Added fixes by XT-0xFF and PrincessOfEvil from the original dev-branch.
• If Melee Animation is loaded, advanced animations will only be used for ranged weapons.
• Thanks to Ferris for most of the 1.5 update work — without them, this would have taken much longer!
• Also check out Yayo’s Combat 3 – Addon by Syrus, which expands ammo handling and adds compatibility fixes for other mods.

Load order

• core
• hugslib
• gunplay
• dual wield

This mod has excellent compatibility. Weapons and armor from most other mods automatically adopt its systems.

If a feature conflicts with another mod, it can be disabled through the options menu.

Incompatible mods: SheathYourSword (all animations will not work)

Recommended mods (not required):

• Combat Sound
• Suppression
• Shield
• Mortar Accuracy

Special thanks: Nemomone3003 (ammo graphic art), Densevoid (coding help), Ferris (1.5 update).
