Extra Battle Upgrades

A combat-focused upgrade pack for R.E.P.O. that expands the game's chaotic survival gameplay with new upgrade builds, enemy control mechanics, sustain systems, and clutch survivability.

The mod is designed around:

• physics chaos
• risky close-range gameplay
• multiplayer cooperation
• scalable endless progression
• vanilla-style balance philosophy

Instead of turning the game into a generic power fantasy shooter, the upgrades are designed to enhance the existing chaos and reward skilled aggressive play.

Armor

Reduces incoming damage.

Each level reduces damage taken.

Damage reduction is always rounded in the player's favor.

Overcharge

Increases how long enemies can be held before overload.

This upgrade slows overcharge buildup, improves overcharge recovery, and increases enemy hold stability while grabbing enemies.

The system modifies:

• overcharge buildup speed
• overcharge recovery speed
• enemy hold duration before escape

Second Chance

Prevents death and grants temporary invulnerability when receiving lethal damage.

Prevents death and grants temporary invulnerability after receiving lethal damage.

When activated:

the player's HP becomes 1

temporary invulnerability activates

health UI changes color

a special yellow heart HUD icon appears while the effect is ready

the icon turns gray during cooldown

Works for lethal damage and death pits.

Energy Leech

A combat sustain upgrade that restores health from damage dealt.

Healing is calculated from ACTUAL enemy HP lost.

Only direct player-caused damage counts.

Examples of valid damage:

• weapon damage
• Shock Grip damage
• tumble launch damage
• held object collisions
• smashing enemies into walls
• damage from objects currently held by players

Invalid damage:

• enemies damaging each other
• fall damage without player involvement
• death pits
• world/environment damage
• uncontrolled physics objects

Healing is granted ONLY to players who actually dealt damage.

Healing is always rounded UP to whole numbers.

Shock Grip

Electrocutes stunned airborne enemies while they are being held.

This upgrade ONLY works when:

• the enemy is stunned
• the enemy is airborne
• the enemy is currently being grabbed

Simple touching does NOT activate the effect.

The upgrade:

• only affects monsters
• does NOT damage players

Shock damage is applied repeatedly while the enemy remains airborne and controlled.

Panic Response

Improves sprint efficiency and helps you escape dangerous situations.

This upgrade passively reduces stamina consumption while sprinting.

When you take damage, Panic Response can also trigger a temporary emergency boost that gives increased movement speed and infinite stamina for a short duration.

The upgrade improves:

• sprint stamina efficiency
• emergency movement speed
• temporary stamina recovery during panic effect
• survival chances after taking damage
