This repository contains custom hardcore waves (ini files) for Killing Floor 2 Endless mode using Custom Zed Waves mutator, as well as a generator of such files from YAML configs with convenient structure. Once you got/generated corresponding ini file, see the mutator's docs on how to use it.

• config A is harder than config B
• config B simply contain all kinds of so-called special waves (consisting of mostly one zed type), whereas more design thought to create more nasty waves is put into config A
• both set of waves can be completed with a decent team, though it might take up to 10 hours depending on your skills
• waves utilize all zeds in the game (including alpha-zeds, bosses, and alpha-Patriarch) available as per May 2018

$ python main.py -h

usage: main.py [-h] [--txt] [--markdown] PATH

Generate `kfzedvarient.ini` file from given YAML config and save it to the
same directory.

positional arguments:
  PATH        path to YAML config

optional arguments:
  -h, --help  show this help message and exit
  --txt       display wave names (default: False)
  --markdown  display wave names in Markdown format (default: False)

• on top of config there are the following meta parameters:
  • n_players: even though the game will automatically adjust a number of zeds depending on the number of players, this might affect zed types ratio or the order in which they spawn; this option, in turn, can provide finer control if you know with how many teammates are you going to play
  • difficulty: used to calculate the number of zeds from [wiki]; for hardcore, only hoe is supported 😈
  • zed_multiplier: a global multiplier of number of all zeds in all waves
  • custom_zeds_ratio_policy and custom_zeds_ratio_policy_params: control the ratio of generated (i.e. custom) zeds, as opposed to zeds generated in KF2 Endless by default; for instance, custom_zeds_ratio_policy: 'make_line_const_interp' and custom_zeds_ratio_policy_params: [[1, 0.975], [20, 0.825]] will gradually decrease the ratio of custom from 97.5% at first wave to 82.5% at 20th, keeping it like that afterward
• after that there are zed-specific options, all of which can be set 1) globally for all waves and all zeds, 2) for all zeds in a specific wave, or 3) for specific wave and specific zed:
  • mutator options spawn_at_once, probability, spawn_delay, number
  • ratio: unnormalized non-negative fraction of certain zed type
  • n_generators: number of "spawners" for certain zed type; can be used to spawn zeds more rapidly (e.g. generate all Stalkers in the waves before zeds of all the other types)
• total number of zeds is estimated from [wiki] using meta parameters n_players and difficulty, after that multiplied by zed_multiplier, and finally computed taking into the account custom_zeds_ratio_policy, custom_zeds_ratio_policy_params
• for boss waves, total zed count is estimated by linearly interpolating between the adjacent waves
• as per [wiki], zeds became to spawn faster in later waves, which was actually way too fast for provided set of waves (causing FPS drop); therefore, the multiplication of all spawn_delays the so-called "spawn delay multipliers" is undone (i.e. divided by); this also enables more transparent control of the spawn delays
