Voidcore Mode
Description
Voidcore mode is one of the two hardcore modes, being the most difficult mode in the entire game. It can only be played by using the center Hardcore Elevator or through the hardcore Matchmaking menu. Like Hardcore mode, Voidcore mode rewards 


Cash is only gained if an enemy is killed, or in some cases, damaged by a specific amount of health. Additionally, the amount gained is a set amount of cash, which is not always equal to the enemy's health. It uses a slightly different method of distributing cash between players, as enemies split their cash between players, regardless of how much damage the player dealt to it. If, in a duo, one player does all the damage to an enemy, both players will receive 50% of the cash the enemy would normally give in solo. This means that in solo, you receive 100% of the cash when an enemy is killed, or it is damaged enough. With each additional player, this is reduced to 50% in duo and 33% If it is a decimal, it gets rounded up or down depending on the decimal value. If it is at least 0.5, it gets rounded up. If it is less than 0.5, it gets rounded down.
Consumables and Skills are disabled in this mode. Shrines also appears in this mode starting from Wave 11, re-appearing every 10 waves.
Rewards
The game calculates how many 






Any rewards that end in a decimal point is rounded down, no matter the first figure of the leading decimal.
Currently, rewards are calculated as:
| Gems Reward | Coins Reward | EXP Reward | Tower EXP Reward |
|---|---|---|---|
Triumphing Voidcore mode can give out an additional reward, which can be a crate, consumable or ticket. They are meant to be guaranteed, though due to a bug this does not always happen. Additionally, items are sometimes not given out. These items are: TBA
Badges
There are also six badges which you can obtain when playing this mode, which may have additional rewards alongside the badge. These are:

Wave Structure
In Voidcore mode, the formula for calculating wave bonus on each wave in is:
- (
$350 + (
$30 × Waves Completed)) ÷ Players
Depending on player count, the wave bonus is reduced using multipliers. These multipliers are:
| Players | Reduction per Player | Total Reduction |
|---|---|---|
| Solo | 0% | 0% |
| Duo | 5% | 10% |
| Trio | 6.7% | 20.1% |
The wave clear bonus does not appear in this mode.

| Wave | Dialogue | Enemy Type & Amount | |
|---|---|---|---|
| 1 | We've got contact inside the Void. I thought this place was supposed to be empty? |
4x Odd, 2x Swift | |
| What? We've been sending research drones into the Void Rifts for months without encountering anything! Hold on. We're setting up the portal now. | |||
| 2 | - | 6x Odd | |
| 3 | Come on, V! We need a way out now. Engineer, we're heading back. |
4x Odd, 3x Swift, 2x Odd (Bloated) | |

| 4 | - | 4x Hefty, 6x Odd | |
| 5 | - | 4x Odd, 2x Swift (Bloated), 4x Odd, 4x Swift | |

| 10 | - | 6x Phantom | |
| 11 | - | 6x Balloon | |
| 12 | It was explained to me by Narrator that the Void is hidden in the depths of the Nil Zone in a place far out of Two X's reach. |
1x Cursed Skeleton (Aggro), 1x Cursed Skeleton (Aggro, Bloated), 4x Phantom, 1x Cursed Skeleton (Aggro, Bloated) | |

| 15 | Where's that portal, V?! |
5x Lead, 1x Elite Lead, 2x Cursed Skeleton, 2x Cursed Skeleton (Bloated, Stun Immune) | |
| We're trying! There's something disrupting the link! From these metrics, it's like the portal is being absorbed before it can even form behind you. I'm tracking the energy drift patterns now! | |||

| 23 | - | 1x Voidling, 8x Mystery, 7x Mandrake, 1x Void Reaper | |
| 24 | It's too late to run, V. I don't know whose attention we've caught, but it doesn't look like it's going to let us leave. |
2x Blighted, 1x Void Reaper, 6x Mystery, 1x Voidling | |
| Commander, readings are showing more hidden enemies heading this way! | |||

2x Voidling, 5x Void Rusher | |

| *Laughter.* Do you hear it? Whispering to you. I do. And it says you will know peace in an everlasting silence. | |||
| Something's affecting The Gate! Energy density is condensing into a central point and being pulled inward! The Void is collapsing in on itself, and the structure is barely holding! | |||
| Argh! Watch out for the shockwaves! | |||
| 31 | - | 1x Mandragora, 8x Mandrake (Bloated), 1x Mandragora, 4x Blighted, 6x Mystery (Bloated, Nimble) | |

7x Void Pike, 6x Void Rusher, 5x Elite Mystery, 6x Void Rusher | |

| 35 | Why? Why do you fight so hard to leave? There's nothing out there that the silence will not reach eventually. Little by little we tear at the seams of your realms, and slowly we watch as they embrace The Void. |
3x Void Reaper, 1x Void Keeper, 1x Elite Phantom (Stun Immune, Freeze Immune, Aggro), 5x Elite Mystery, 1x Elite Phantom (Stun Immune, Freeze Immune, Aggro) | |
| Our world is not for you to destroy! You won't-... no. No! Why are there two bosses?! | |||

| 39 | We stabilized The Gate for now, but it won't hold. We're actively searching for this girl's voice, but it's coming up scattered. It's like she's nowhere but everywhere all at once. |
4x Elite Mystery, 3x Slow King, 6x Unknown Small, 3x Speedy King | |
| Well it's either her or us. I need a way to make sure it's not us. We're running out of options here. | |||
| 40 | Whatever this thing is, it's barely taking any damage! Wait, did you see that? Right as it uses an attack? |
1x Crystalian (Boss), 2x Slow King, 5x Elite Void Rusher, 1x Void Titan (Freeze Immune) 8x Unknown Small, 1x Speedy King | |
| Dodge the attack and shoot it before it recovers, quick! | |||
| 41 | Where are these souls coming from? |
6x Soul (Bloated), 3x Elite Soul, 3x Slow King (Aggro), 6x Soul (Bloated) | |
| Did you really believe your realm was the first to find silence? *Laughter.* | |||
| 42 | - | 3x Mandragora (Bloated), 1x Void Trickster, 8x Elite Mystery, 4x Nightshade, 6x Unknown Small | |
| 43 | We're picking up significant cumulative energy nearby. Our sensors can barely track how much is being pulled in and then it's just... vanishing. |
7x Nightshade, 1x Void Titan, 6x Void Floater (Blessed), 6x Unknown Small (Bloated), 1x Void Titan, 3x Slow King, 1x Vindicator (Boss), 1x Void Trickster, | |
| The team isn't going to make it much longer. We need a plan B. V, you need to promise me. If we don't make it, that gate closes with or without us. | |||
| Just make it out alive, okay? | |||
| 44 | - | 3x Elite Soul, 1x Unknown Boss, 5x Soul (Bloated), 1x Unknown Boss, 5x Unknown Small, 1x Unknown Boss, 1x Void Cultist, 5x Elite Void Rusher (Bloated) | |
| 45 | What is that? Everyone get back! Engie? Engineer! V, it's taking Engineer's soul! I need everyone focusing fire on that monster! |
6x Soul (Bloated), 5x Elite Soul, 4x Slow King (Aggro, Bloated), 3x Void Titan (Freeze Immune), 1x Void Cultist, 1x Soul Stealer (Boss), 7x Soul (Bloated), 2x Unknown Boss | |
| We are freeing them of their burden. To drag them back to flesh and suffering? Only your kind would call that mercy. | |||
| 46 | Engineer? Are you alright? |
1x Heavy Voidling, 3x Elite Void Rusher (Nimble), 1x Void Trickster, 3x Elite Void Rusher (Nimble), 1x Slow King (Blessed, Bloated), 3x Elite Void Rusher (Nimble), 5x Slow King (Bloated), 6x Soul, 1x Heavy Voidling, 3x Speedy King (Aggro), 4x Speedy King | |
| *Cough*... If that happens to me again, please kill it quicker. That just felt... wrong. | |||
| 47 | - | 4x Elite Soul, 4x Unknown Boss, 2x Heavy Voidling, 2x Void Titan (Freeze Immune), 1x Void Knight, 1x Crystalian (Bloated), 3x Void Cultist | |

| The Gate is turning into scrap metal and more Void Rifts are popping up. We need to finish whatever 'this' is and leave! | |||
| Take cover before it slices us in half! I want all guns on the target now! | |||
| The time is upon us. Now, the Void will call out to you. And it will be best to listen as you soon rest your head in a bed of flowers. | |||
| 49 | - | 8x Nightshade, 6x Slow King (Blessed, Bloated), 3x Void Knight, 1x Void Guardian, 10x Nightshade 3x Void Trickster, 10x Nightshade, 1x Void Cultist (Health Regen), 6x Slow King, 10x Elite Void Rusher (Blessed), 3x Speedy King | |
| 50 | When the Old World still drew breath, Lord Exo saw what I was, what I have been always been, and accepted it. My army marched beneath his banner as I gave him a promise that the flora of the Void would take root in every realm and bloom, until there was nothing left to bloom upon. Now you will watch as your world dies a quiet, tranquil death. |
