Description

Intermediate mode is one of the five main survival modes. It has 30 waves, and the final boss is Patient Zero.

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, 33% in trio and 25% in quad. 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. For example, the Hidden Boss gives $600 when killed in solo, $300 in duo, $200 in trio and $150 in quad between the players that damaged it.

Rewards

For former rewards, see this mode's Rewards page.

The game calculates how many Coins 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. Some maps like Mason Arch can also increase all rewards by a specific amount. Regular EXP boosts are multiplicative with other modifiers.

Any rewards that end in a decimal point is rounded down, no matter the first figure of the leading decimal.

Rewards are calculated as:

Coins Reward	EXP Reward
500 ÷ (1 + [(30 ÷ Current Wave) - 1]^1.3) + 100 (Triumph Only)	120 EXP ÷ (1 + [(30 ÷ Current Wave) - 1])

Triumphing Intermediate 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:

• Common (65%)
  • Time Scale Ticket
  • Revive Ticket
  • Grenade (1-3)
  • Flash Bang (1-3)
  • Molotov (1-3)
• Uncommon (20%)
  • Low Grade Consumable Crate
  • Spin Ticket
  • Barricade (1-2)
  • Supply Drop (1-2)
  • AirStrike (1-2)
• Rare (10%)

Wave Structure

In Intermediate mode, the formula for calculating the wave bonus on each wave is:

$200 + (Waves Completed - 1) × $150

Depending on player count, the wave bonus is reduced using multipliers. These multipliers are:

Prior to the 11th of September 2024, the formula for calculating the wave bonus depended on the wave. They were:

• Between Waves 1-10 and on Wave 30:

  ($200 + (Waves Completed - 1) × $150) ÷ (1 - 0.08 × Players)

• Between Waves 11-20 and on Wave 30:

  ($200 + (Waves Completed - 1) × $200) ÷ (1 - 0.08 × Players)

• Between Waves 21-28 and on Wave 30:

  ($200 + (Waves Completed - 1) × $350) ÷ (1 - 0.08 × Players)

• On Wave 29:

  $15,000 ÷ (1 - 0.08 × Players)

The wave clear bonus appears when every enemy from that wave was killed. It is 35% of the wave bonus in solo, while for duo, trio and quad it is 20%.

The waves in Intermediate mode follow these timings:

Bolded names indicate an enemy type's debut.

There is a total of 766 enemies in Intermediate mode excluding enemies that are summoned.
