Recoil (no ontology)

From Mazeworld

The basic premise of the recoil system is to simulate the increasing spread and loss of accuracy as one fires more rounds from a firearm.

Recoil only comes into play when using relevant firearms (Pistol, Rifle and Shotgun calibers), and only when firing at least more than one shot continuously in a single turn. It doesn't apply in any other circumstances.

Recoil and ADT

As mentioned above, at least more than one shot must be fired in a single turn for Recoil mechanics to begin entering into play. Fire mode does not matter.

  • NOTE: If a weapon's caliber does not have a Recoil value but is capable of firing multiple shots (e.g. certain grenade launchers, etc.), then Recoil doesn't apply.

Eight different Recoil levels exist. The Recoil level determines the Accuracy Drop Threshold (ADT) and the effects of going over that threshold. ADT essentially determines how many successive shots can be fired in a single turn without suffering from the listed effects. When ADT displays an amount of shots equal to X, then this weapon can fire X shots without feeling effects from the recoil. In other words, every shot after the Xth means a negative effect is applied. The pattern repeats for each multiplier of X shots fired.

  • Example: If the ADT for a given recoil level is "8 shots", then the first 8 shots can be fired without negative effects from recoil (shots 1-8). The next 8 will suffer from one instance of the effect (shots 9-16), then the next 8 will suffer from two instances (shots 17-24), and so on.

The effect of going over ADT also depends on the Recoil level: it may consist of an increase in Inaccuracy Range, or for particularly high Recoil levels, a flat increase of the Failure Threshold.

Recoil levels

  • Recoil 1 - None
    • ADT: 12 shots (1-12, 13-24, 25-36...)
    • Effect: Inaccuracy Range increases by 1
  • Recoil 2 - Low
    • ADT: 10 shots (1-10, 11-20, 21-30...)
    • Effect: Inaccuracy Range increases by 1
  • Recoil 3 - Medium
    • ADT: 8 shots (1-8, 9-16, 17-24...)
    • Effect: Inaccuracy Range increases by 1
  • Recoil 4 - Heavy
    • ADT: 6 shots (1-6, 7-12, 13-18...)
    • Effect: Inaccuracy Range increases by 2
  • Recoil 5 - Punishing
    • ADT: 4 shots (1-4, 5-8, 9-12...)
    • Effect: Inaccuracy Range increases by 2
  • Recoil 6 - Brutal (affectionately: "Ouch", "Why?")
    • ADT: 3 shots (1-3, 4-6, 7-9...)
    • Effect: Failure Threshold increases by 1 + Inaccuracy Range increases by 2
  • Recoil 7 - Extreme (affectionately: "Masochism", "Coming through!")
    • ADT: 2 shots (1-2, 3-4, 4-6...)
    • Effect: Failure Threshold increases by 1 + Inaccuracy Range increases by 2
  • Recoil 8 - Insane (affectionately: "It may as well fly off of my hands", "LOW EARTH ORBIT DEVICE")
    • ADT: 1 shot (1, 2, 3...)
    • Effect: Failure Threshold increases by 1 + Inaccuracy Range increases by 2

Sectioning strings of fire

When firing a string of shots, the shots are grouped into sections depending on the recoil level and ADT. For example, at Recoil 3, a string of shots would be grouped into sections of 8 shots. Examples of sections are displayed above, to the right of the ADT value of each recoil level.

  • The first section represents the accuracy window: the section of shots that sustains no negative effects from recoil.
  • Every section after the first is affected by the effects of recoil.
  • Additionally, valid for all recoil levels, every section after the first will land on a random body part of the target, instead of the intended point of aim. This simulates the ever-widening spread of projectiles as recoil (and subsequent inaccuracy) increases.

Example: A Kalashnikov AKM, which is chambered in 7.62x39mm, is considered to be Recoil 3 when loaded with standard FMJ ammunition. A string of 14 shots fired with such a weapon would be sectioned this way:

  • Shots 1-8 - followed by the tally of dice score for the first 8 shots, and the total amount of hits and misses.
  • Shots 9-14 - first followed by the body part these shots land into (due to ADT), next by a mention about the effect of the current section (in this case, it would be IR+1), then by the tally of dice score and the total amounts of hits and misses.
Special cases

Recoil level not only depends on the caliber, but also the pressure level of a given round. As such, it is possible that a given string of fire in a single turn may include rounds of varying Recoil level (for instance, when mixing -P, SP and +P ammunition in the same magazine then firing them).

  • Example: A shooter using an H&K MP5A3, a submachine gun chambered in 9x19mm Parabellum, shoots a string of 20 rounds in full-auto which includes a mix of 9 SP, 7 +P and 4 +P+ rounds.

If such a situation occurs, then the highest pressure level fired during that specific string of fire is checked, and applied to the entire string as though all shots fired were of that pressure level.

  • Example: Despite the fact that out of the 20 rounds fired in the example above, only four were +P+ rounds, all 20 rounds fired are treated as though they were +P+. 9x19mm Parabellum is Recoil 2, and +P+ adds 2 recoil levels - therefore all 20 rounds would be considered to be Recoil 4.

Keep in mind that recoil modifiers from other sources (e.g.: accessories) are counted AFTER modifiers from ammunition, including in the above case of mixed ammunition in a single string of fire.

  • Example: Luckily, the H&K MP5 is equipped with a muzzle brake (Recoil -1), which helps mitigating the recoil level. The string of fire's final Recoil level is reduced to 3, which means the 20 shots will be cut in three sections; 1-8, 9-16, and 17-20.
