Gameplay mechanics (Killing Floor 2)

Money

Dosh is the new currency in Killing Floor 2, replacing the pound sterling from the first game. Dosh is used to buy equipment at the Trader.
Players can share money between each other by throwing it in stacks of 50 Dosh. Thrown money disappears after 2 minutes if not picked up.

Starting Money

New Game

Each player receives money at the start of a game based on difficulty.

	Normal	Hard	Suicidal	Hell on Earth
Starting money	300	250	200	100

Mid-game

Players joining a game that has already started will get money based on the current wave of the game.
For example, in a long game, players joining during the first wave will receive 10% of the respawn money while players joining during the final normal wave will receive the full value.

Starting money = Respawn money * (current wave / max wave (excluding boss wave))

	Normal	Hard	Suicidal	Hell on Earth
Respawn money	1750	1550	1550	1000

After Death

There is a penalty for dying, based on difficulty.

Starting money = Money - (money * death penalty modifier)

	Normal	Hard	Suicidal	Hell on Earth
Death penalty modifier	5%	10%	20%	25%

However, if a player has less money after the death penalty than a newly joined player would have, the player will instead receive that same amount of money.

Earning Money

Killing Specimens

Money is earned through killing specimens. Each specimen has a Dosh value which is modified and distributed to all damaging players once the specimen is dead.
The final value earned for each player is based on difficulty, the number of players in the game, and the amount of damage done to the specimen (in %).

Money earned = (Specimen value * difficulty modifier * (number of players / player modifier)) * (damage done / total damage done)

	Cyst	Clot	Slasher	Crawler	Stalker	Bloat	Gorefast	Siren	Husk	Scrake	Fleshpound	Hans Volter
Specimen value	7	7	7	10	15	17	12	25	17	75	200	500

	Normal	Hard	Suicidal	Hell on Earth
Difficulty modifier	110%	100%	85%	65%

	1	2	3	4	5	6
Player modifier	100%	200%	275%	350%	400%	450%

Surviving A Wave

Each player surviving a wave will receive bonus money taken from the pool of money that the team has earned over the wave.
There is a death penalty that applies to the pool of money that the team has gathered whenever a player dies, except on Normal.

Money earned = (Money earned by each player this wave - team death penalties) / surviving players

Team death penalty = Money of the dead player * difficulty modifier * 5%

	Normal	Hard	Suicidal	Hell on Earth
Difficulty modifier	0%	100%	200%	300%

Experience

Experience is gained by killing specimens. Each specimen is worth a certain amount of experience points, depending on difficulty. Whenever a specimen dies, any player who damaged it receives its full experience value.

Each perk has its own experience and level which starts at 0 and caps at 25. Experience for a perk is primarily earned by using its class weapons. Using off perk weapons does not result in any experience gain except for the 9mm Pistol, which gives experience to the selected perk. Damaging a specimen with multiple class weapons splits the experience points between the perks. Each perk also receives bonus experience for performing various actions, see each perk page for specific details.

Level	Experience required	Level	Experience required
1	2,640	14	9,667
2	2,917	15	10,683
3	3,224	16	11,804
4	3,562	17	13,044
5	3,936	18	14,413
6	4,349	19	15,927
7	4,806	20	17,599
8	5,311	21	19,447
9	5,868	22	21,489
10	6,484	23	23,745
11	7,165	24	26,238
12	7,918	25	28,993
13	8,749

Trader

Once all specimens in a wave have been killed, the trader opens up for a limited time before the next wave begins. The opening time is 90 seconds on Normal and 60 seconds on Hard, Suicidal and Hell on Earth.
The trader and the trader rooms from Killing Floor have been replaced by trader pods. Players can buy, refill and sell equipment while standing close to a trader pod.

Waves

Lengths

The number of waves for a short, normal and long game is retained from Killing Floor. In addition to the standard waves, there is also a final wave where the boss appears.

	Short	Normal	Long
Wave length	4	7	10

Number Of Specimens

Each wave has a set number of specimens that will spawn, differing depending on game length. The number is affected by difficulty and the number of players in the game.

Total specimens per wave = Specimens per wave * difficulty modifier * player modifier

Specimens per wave
	1	2	3	4	5	6	7	8	9	10
Short	25	32	35	42
Normal	25	28	32	32	35	40	42
Long	25	28	32	32	35	35	35	40	42	42

	Normal	Hard	Suicidal	Hell on Earth
Difficulty modifier	85%	100%	130%	170%

	1	2	3	4	5	6
Player modifier	100%	200%	275%	350%	400%	450%

Specimen Appearances

Specimen squads are randomized. There is also a special squad that spawns each wave which contains tougher specimens. On Suicidal and Hell on Earth difficulty, the special squad can be recycled, which means these difficulties will spawn tougher specimens on average.
