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. In solo, you receive 100% of the cash when an enemy is killed, or it is damaged enough. With each additional player, this decreases by 25%, which means that in a quad, you only get 25% of the cash. This amount is distributed between players based on how much damage they dealt. However, if a player has not dealt any damage, they will receive a percentage of the enemy's full cash upon its death or when it was damaged enough, which is 12.5% in duo, 16.7% in trio and 18.75% 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,
$450 in duo,
$300 in trio and
$150 in quad between the players that damaged it. Players that did not damage it receive
$75 in duo,
$100 in trio and
$113 in quad.
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 ā 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 |

Wave Structure
In Intermediate mode, the formula for calculating the wave bonus on each wave is:
$200 + (Waves Completed - 1) Ć
$150
Depending on player count, the wave bonus is reduced using multipliers. These multipliers are:
Players | Reduction per Player | Total Reduction |
---|---|---|
Solo | 0% | 0% |
Duo | 6% | 12% |
Trio | 7% | 21% |
Quad | 6% | 24% |
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) Ć
$150) Ć· (1 - 0.08 Ć Players)
- (
- Between Waves 11-20 and on Wave 30:
- (
$200 + (Waves Completed - 1) Ć
$200) Ć· (1 - 0.08 Ć Players)
- (
- Between Waves 21-28 and on Wave 30:
- (
$200 + (Waves Completed - 1) Ć
$350) Ć· (1 - 0.08 Ć Players)
- (
- On Wave 29:
$15,000 Ć· (1 - 0.08 Ć 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:
Waves | Wave Timer | Skip Time[4] |
---|---|---|
1-29 | 1:00 | 0:19[5] |
30 | ā | N/A |
Bolded names indicate an enemy type's debut.
