Stealth Camo (Special Item)
Stealth Camo (Special Item): makes you invisible from enemies. You can obtain it only by finding and shooting all 64 Kerotans, or by beating the game with zero alerts.
No Alerts
Always use the most suitable camo combined with AT-Camo. Moss for grass areas that can give you up to 95% camo index while replenishing your stamina in daily outdoor areas, Splitter or Squares for urban zone. Use Spirit camo, that makes your footsteps noiseless, for enemies that you can tranquillize from behind with CQC or Cig Gas Spray. (For full camo guide see Complete Camo and Face Paints Guide).
No Special Items
Special items are Stealth Camo, Infinity Face Paint and EZ Gun. AT-Camo and Patriot are not special items.
