Wave	Dialogue		Enemy Type & Amount
1	Professor V	Commander, with the defense system down, the zombies are making their way through the city to your location. Reactivating them will take some time before everything is fully operational.	4x Normal, 3x Speedy, 4x Normal, 3x Speedy
	Commander	Understood. Recruit, you heard her! Set up our defenses and prepare for the horde! Everyone else, hold position!
2	Trapper	Alright! Now we're talking! Hopefully they'll let me stay in the city after we save their skin. They're uh—... not all that happy with me right now.	6x Speedy, 12x Normal (Bloated)
	Sniper	Let me guess: Bear Trap?
	Trapper	What? Can't they have a little sun? It's his fault for not looking.
3	Soldier	I hope V's right about the tunnels. If the system comes up before Hops and Demo make it out, they'll be stuck with those things. Hah — but I know they'd collapse the entire mine if they could.	6x Normal, 3x Breaker2, 4x Speedy, 6x Normal
	Commander	The best we can do is take out as many zombies as we can. That way they only have to worry about what's behind them.

5	-		6x Normal (Bloated, Nimble), 3x Breaker2, 4x Breaker2 (Bloated), 1x Normal Boss (Boss)
6	Professor V	Ugh! The southern core isn't powering up! This system was built before I was palced on the project, so they're using some seriously old tech. This was never designed to be turned off in sections.	6x Speedy (Bloated, Nimble), 4x Breaker2 (Bloated), 4x Breaker2 (Nimble), 6x Speedy (Bloated, Nimble), 1x Normal Boss, 6x Speedy (Bloated, Nimble)
	Professor V	Something must have chewed through the wiring on its way in. I'm heading there now with a repair crew. Let's cross our fingers it's something fixable.
7	-		4x Breaker2 (Bloated), 1x Normal Boss (Bloated), 8x Speedy (Bloated, Nimble)
8	Soldier	They seriously didn't have a backup plan for a situation like this? You've got to be kidding me!	2x Enraged, 1x Normal Boss (Bloated), 5x Normal (Bloated), 4x Breaker2, 1x Normal Boss (Bloated)
	Sniper	It's not that. From what I've heard in headquarters, manufacturing plants are being overrun with infected and— Get off me! Arg... I doubt Cyber City can get the materials to even build a backup plan.
9	-		5x Breaker2 (Bloated, Nimble), 6x Hidden, 5x Breaker2 (Bloated, Nimble), 6x Hidden
10	Trapper	Hey zombie, catch! Yeah! Haha! Come here! Watch out for Mr. Nibbles!	2x Enraged, 1x Enraged (Bloated), 2x Normal Boss (Bloated), 7x Hidden, 10x Normal, 2x Enraged, 1x Enraged (Bloated)
	Commander	... Mr. Nibbles? You name your traps?
	Trapper	Hah, wait until you hear about Betsy—... I LEFT BETSY INSIDE THE MINE.
11			1x Normal Boss (Bloated, Nimble), 7x Armored, 6x Skeleton, 1x Necromancer (Boss)
12	Dispatcher	Commander, come in. I heard from V that you've made it into the city. There's something heading your way that's— and destroying the radio towers.	5x Armored, 4x Hazmat, 8x Hidden (Bloated), 4x Enraged (Bloated), 10x Normal (Bloated), 6x Armored, 4x Hazmat
	Dispatcher	It broke through the gates of the city. They're already moving the citizens further back into the bunkers.

14	Professor V	Agh! You stupid thing! There! The crystal core is back online. The zombie who bit the wire is fried to a crisp.	4x Hazmat (Bloated), 11x Speedy (Bloated), 9x Breaker3 (Nimble), 9x Hidden (Bloated, Nimble), 12x Armored (Bloated)
	Professor V	It will have to spin up before we can turn on the system. Hold on, Commander, we're almost there.

	Commander	It's got to be a few blocks away. Minigunner, cover the survivors and get them inside the building!

	Commander	V we need those guns up! What's taking so long?!
	Professor V	Almost there! A few more minutes!
	Trapper	Oh, I'm down to my last traps... What a horrible day...
20	Professor V	Yes! Systems are coming online! Everything's booting up! We've almost got it!	6x Enraged (Bloated), 6x Normal Boss (Bloated, Nimble), 7x Hazmat (Bloated), 1x Slow Boss, 4x Bolt, 8x Armored (Bloated, Nimble), 1x Speedy Boss, 1x Grave Digger, 1x Breaker4, 4x Breaker3, 1x Breaker4, 4x Breaker3, 1x Breaker4, 4x Breaker3, 1x Breaker4, 4x Breaker3

Trivia

• Professor V's dialogue is bugged on Wave 20 and it uses the wrong audio. However, although it may sound exactly the same as the audio used by the Sniper immediately after, that is actually not the case. Professor V's dialogue plays a different Grave Digger roar in the background.

Update History

  • Lights Out added.
  • Bug: The first dialogue on Wave 20 uses the wrong audio.
