[Verse 1: Attackers]
Knock knock, who's there?
Let me check your Pulse, are you scared?
Knock knock, better run, hide
Get to cover and listen for the punchline
This countdown's tickin', is it crunch time?
Smile for Twitch, this stream is up, live
Sneak in and have Thatcher dispatch ya
Got a short Fuze 'cuz I have a blast as an attacker
Reducing your Castle to Ash
Got the eyes of a Jackal, it's a house of Glaz
Take a Sledgehammer to your cameras, smash
Hand you a Buck 'cuz your defense is cashed
Me steppin' in your trap won't happen
Predictable, put a cap in Kapkan
Keep my head in the battle while my shield is active
And my Blackbeard alone will keep 'em distracted
Campers, pack your bags and go
I'll smoke you out like a tactical Capitao
I'm on Rambo's level with this action, bro
You never cross a man who has a bow
I'm a one-man army, if you wanna stop me
Then you gotta pry this armor off my body
I'm an immovable object, comme la Montagne
Call me Monty, or just Tachanka's bane
Shit'll hit the fan, it'll go ballistic
As if Vigil got slammed with a Blitz hit
Listen, my new hire IQ has got a higher IQ than I do
And I'm a science nerd, because I like to learn
What I can burn, what can Thermite do?
Boom! Now we're talkin' home improvement
Called Hibana's demolition crew in
Operator, make your move
If I had to guess your class, I'd say Recruit
[Refrain]
Follow my lead, we'll break 'em down
Stick with the operation
Think of the lives we're savin' now
Throw out negotiation

[Hook]
Knock knock, anybody answer?
Knock knock, did you bring your hammer?
Knock knock, what are they demanding?
Do they feel protected? They're taking that for granted
Knock knock, we're comin' through the doors
Knock knock, the ceilings and the floors
Knock knock, I should've said before
No negotiation, we're giving you a war


[Verse 2: Defenders]
Knock knock, who's there?
Take a peak inside, if you dare
How many hostages will you spare?
How many toxic fumes can you bear?
Don't choke, but you know to fear us
We're so much more than Smoke and Miras
Is it just your reflection that's starin' back?
Careful in the future, that mirror's black
It's a hell of a time fightin' Ela
With dizzy spells, shittin' yourself, so get back, fella
Whoops, sorry Ying, are you jealous?
Tell us, did you bring a cake for the candelas?
Oh, don't forget your headphones
I'll concuss ya with ultrasonic Echoes
And then I'll call you a Doc if you got the headspins
Pop a couple shots of Epinephrine
Whoa, go easy with the Jäeger, ma'am
Zofia, way to get grenades wasted, damn
I just armed the bomb, left the rest to Bandit
When his wire gets tripped, he will amp it
So before you enter, step on the Welcome Mat
It's a Frosty night, I can tell you that
Now freeze, while I'm dishing out diseases
In these needles, check your body for Lesions
Look, Rook, can we get some armor on?
Hopefully Dokkaebi's got more than logic bombs
Even if she does, we got our Valkyrie
Keeping an eye out for me, that's how I sneak
Up on your back with Cav, and stab you
You better answer any question that I ask you
I've pushed all your buttons, you don't have Mute
But all you'll hear is silence when I hack you
We'll send you packing, that's a wrap for you
Now ask yourself: who was attacking who?
[Refrain]
Should all the walls come cavin' in
You know the operation
Facilitate detonation
Throw out negotiation

[Hook]
Knock knock, get ready to answer
Knock knock, forget about your manners
Knock knock, keep 'em from advancing
It's our last stand, to the death I will defend it
Knock knock, barricade the doors
Knock knock, the ceilings and the floors
Knock knock, if you want a war
Step into my house, and we're gonna give you more
