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 Gems instead of Coins, but unlike Hardcore mode Coins can be earned upon successful completion of this mode. You need to first triumph Hardcore mode and be at least Level 50 to play this mode.

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 Gems and EXP you receive based on how many waves you survived and if you won a match. During periods of 100% more EXP (Friday – Sunday), any EXP earned is multiplied by 2x through the XP Boost modifier. The VIP gamepass also multiplies any EXP earned by 1.25x through the VIP Boost modifier. These two boosts are additive. These EXP bonuses multiply EXP after it has been multiplied by modifiers.

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
250 ÷ (1 + [(50 ÷ Current Wave) - 1]^3) + 450 (Triumph Bonus)	1,000 (Triumph Bonus)	200 EXP ÷ (1 + [(50 ÷ Current Wave) - 1]) + 300 EXP (Triumph Bonus)	190 EXP ÷ (1 + [(50 ÷ Current Wave) - 1]) + 230 EXP (Triumph Bonus)

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

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.

The waves in Hardcore mode follow these timings:

	Commander	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.

	Professor V	The Gate is turning into scrap metal and more Void Rifts are popping up. We need to finish whatever 'this' is and leave!
	Commander	Take cover before it slices us in half! I want all guns on the target now!
	Void Caster	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	Void Caster	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.	1x Vindicator (Bloated), 7x Slow King (Blessed, Aggro), 1x Void Cultist, 4x Unknown Boss, 1x Heavy Voidling (Nimble), 7x Elite Void Rusher (Blessed), 5x Void Titan, 1x Void Guardian, 1x Heavy Voidling (Nimble), 7x Elite Void Rusher, 4x Void Knight, 1x Void Trickster, 1x Void Guardian, 1x Void Reaver

	Void Caster	Hah. You carry the will of a fool.
