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

Each level reduces damage taken by 5%.

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

Overcharge

This upgrade slows overcharge buildup and improves overcharge recovery while grabbing enemies.

The system modifies both:

• overcharge buildup speed
• overcharge recovery behavior
