📌 Feature Suggestion: Operation Last Light (Post-Mexico Mode Expansion)

After completing Mexico Mode, players unlock a new game mode focused on fully eliminating the infection instead of just surviving.
Core Concept:
-Players start with 5 vaccine vials.
-The objective is to travel across the map and rescue infected scientists.

Labs spawn randomly, similar to the bank code system.
Dynamic World-State System
This mode changes based on previous runs:
If Tesla was revived and defeated before, labs become more dangerous with electric zombie variants, automated security systems, and unstable power fields.

If Tesla was never revived, the infection is less evolved and labs are safer.

This creates replay value and makes past decisions meaningful.
Vaccine Crafting System
Players must collect specific liquids from the world to complete the cure.
Examples:
-Zombie blood
-Acid
-Water
-Rare creature blood (e.g., unicorn horse blood)

Final Objective:
After rescuing all scientists and completing the cure formula, players must return to Ground Zero and deploy the vaccine to trigger the true ending.
