Implants Guide

🧬 Overview

Alone Implants features 10 cybernetic augmentations divided into two categories:

• Active Implants (5) — Require a key press to activate, installed on the body map

• Passive Implants (5) — Always active once installed, placed in the 4 passive slots

⚡ Active Implants

Active implants are installed by dragging them onto body map sockets. They consume heat, have cooldowns, and lose durability on use.

🔄 Upgrade System

All implants can be upgraded from Level 1 to Level 3:

1. Install the implant at Level 1

2. Select the installed implant (click on the socket or passive slot)

3. Click "Upgrade" in the Info Panel

4. Pay the cost (if configured via Config.ImplantOverrides)

Upgrade cost formula:

Cost = BaseCost × CurrentLevel × Config.Economy.UpgradeCostMultiplierPerLevel

⚔️ Incompatibility System

Some implants conflict with each other and cannot be installed simultaneously:

Implant	Incompatible With
Double Jump	Sprint Boost
Sprint Boost	Double Jump

If you try to install an incompatible implant, you'll receive an error notification.

Tip: You can customize incompatibilities using Config.ImplantOverrides:

Config.ImplantOverrides = {
    dash = { incompatibleWith = { 'sprint_boost' } },
}

📊 Heat Management

Each active implant generates heat when used:

Implant	Heat Cost	Category Decay Rate
Double Jump	12	0.8/s (locomotion)
Dash	15	0.8/s (locomotion)
Sprint Boost	18	0.8/s (locomotion)
Night Optics	6	0.7/s (utility)
Adrenal Burst	22	0.6/s (combat)

When heat reaches 100 (default max), the system enters Overheat:

• All active abilities are disabled for 20 seconds (configurable)

• Sprint speed is reduced by 10% (if debuff is enabled)

• The Cooldown HUD shows a red overheat indicator
