Battlefield 1/Neebs Air Assault
On the Air Assault maps Razor's Edge, London Calling: Scourge and London Calling: Raiders, part of the Apocalypse expansion pack, Neebs from Battlefield Friends can be heard yodeling and shouting when certain parameters are set.
On Razor's Edge, Neebs can be heard yodeling and shouting that he is a terrible pilot. The exact parameters to active either quote is unknown, however, it is believed that flying close to the mountain has a chance to active the yodeling.
On either of the London Calling maps Scourge or Raiders, the gunner of a British side plane can hear Neebs saying various "bailing out" quotes. To have a chance of hearing Neebs, the pilot must either redeploy or switch to another seat on the plane. This will cause the pilot to say different generic quotes, but sometimes Neebs will say some of his own. Neebs' quotes are client sided, meaning not all players on the plane will hear it.
All quotes by Neebs:
Take the sticks, she's all your.
Take the sticks, I'm getting bored.
Alright, you're on your own, sucker!
You're on your own, sucker! Hahahahaa!
Take the sticks, I'm bailing out, you're on your own, sucker!
Take the sticks, I'm bailing out, by the way, the left wing's missing.
Take the sticks, I'm bailing out, by the way, I'm taking the left wing with me.
Note that some quotes indicate that the left wing is missing even though the plane is at full health.
