🌑 Stealth Mechanics:

1. Stealth Meter (Top Right of HUD)

• Starts at 100%
• This represents how hidden/undetected you are
• If it drops to 0%, you're COMPROMISED and the mission fails

2. Shadows (Dark Black Areas)

• The darker rectangular zones on the map are shadow zones (safe areas)
• When you're inside a shadow:
  • ✅ Your character glows GREEN
  • ✅ Your stealth meter increases (recovers)
  • ✅ Guards cannot see you even if you're in their vision cone (red areas)
  • You're completely hidden!

3. Being Exposed (Outside Shadows)

• When you're outside shadows:
  • ⚠️ Your character glows YELLOW
  • ⚠️ Your stealth meter slowly decreases
  • ⚠️ If guards spot you in their red vision cones = INSTANT DETECTION = Mission Failed!

4. Strategy:

• Plan your route using the shadows as cover
• Sprint between shadows when guards are looking away
• Watch your stealth meter - if it's getting low, hide in shadows longer to recover
• The Stealth Recovery upgrade makes your meter regenerate faster in shadows
• The Shadow Master upgrade makes shadow zones bigger, giving you more safe space

TL;DR: Shadows = Safe (Green player, invisible to guards). Open areas = Dangerous (Yellow player, visible to guards). Stay in shadows as much as possible! 🕵️

Now you can strategically invest in upgrades to make later levels easier! Good luck, agent! 🎮
