Allows Sniper to detect and do an additional 2 damage to Camo bloons.
~ BTD6 description as of Version 11.0
Night Vision Goggles is the first upgrade of Path 2 for the Sniper Monkey in BTD6. This upgrade allows the Sniper Monkey to detect Camo Bloons, like in BTD5, but additionally allows the Sniper Monkey to deal +2 damage to Camo Bloons.
Night Vision Goggles not only gives the Sniper with the needed camo popping power, it also makes the Sniper an effective option at specifically countering Camo Bloons.
While it is a alright upgrade, overall, the power from the Top Path is better for the Bottom Path Sniper, while for Top Path the Bottom Path adds more speed to the Sniper.
Don't completely discount this upgrade for either path, however, because a 0-2-5 Sniper can solo Deflation.
On Easy difficulty, a 2-2-0 Sniper can take care of all Camo-Bloons.
A 3-2-0 and a 0-2-4 Sniper can handle all camos on Medium difficulty. You'll need a lot more firepower to handle round 78, though, making this strategy unfeasible for Hard difficulty or higher.
Creatively, a buff for Path 2 crosspathing has been given to this upgrade by allowing the bullet to deal extra damage to Camo Bloons, starting from Version 11.0.
Night Vision Goggles now allows the Sniper Monkey to deal +2 damage to Camo Bloons. Only affects main bullet.
Affected by base Sniper attack speed buff
Crosspathing in BTD6 (Top: Path 1, Bottom: Path 3)
Updated BTD6 description of Night Vision Goggles (Version 11.0)
Night Vision Goggles dealing 4 damage to a Camo White, due to +2 damage to Camos
In BTD6, the description for the Night Vision Goggles was modified in Version 11.0 from "Allows the sniper to detect and shoot Camo Bloons." to the new description to fit the addition of the new bonus damage to Camo Bloons.
This is the first upgrade in BTD6 that does increased damage to a bloon with a special property other than Fortified, Lead, Ceramic, or MOAB-class.
It remained the only upgrade (including its derivatives) to deal extra damage to camo, until Sauda was released in Version 24.0. Her Level 19+ upgrade allows her to deal extra damage to various bloon types.
