Move Speed is a stat: Speed of movement in cells per second (c/s). A default Human has a base movement speed of 4.6 c/s.

Factors[edit]

Offsets[edit]

First of all the following offsets are applied to the Move Speed Base value.

Factors[edit]

The following factors are applied after the Offsets.

External factors[edit]

Weather[edit]

  • Rain and Foggy rain: ×90%
  • Rainy thunderstorm and Hard snow: ×80%

Path cost[edit]

Floors, buildings, items and plants add path cost. Where each path cost adds about 7.7% to the time it would take the pawn to traverse this tile unhindered. The move speed factor can therefore be calculated like this:

move speed factor = 1 / (1 + path cost * 0.077)

For terrain, flooring and things with a path cost of 20 or below, a pawn is slowed down every time they enter a tile with that thing. For things with a path cost of 25 or above continuing walking on a thing with a path cost of 25 or higher doesn't slow the pawn down again (even if it gets higher).[Fact check] Walking over an item on a workbench slows the pawn down again, items on shelves have no additional effect, however.

Below is a selection of some common values. Minified things have a path cost of 14.

Flooring and terrain[edit]

For flooring and terrain see the full list below. Note that pawns are slowed down continuously by terrain, but things on top of it with a path cost equal or below it, don't slow the pawn additionally.

    Rough stone 0.87
    Rough-hewn stone 0.93

      • Sand: ×76%
      • Lichen-covered soil: ×81%
      • Soil, Stony soil, Rich soil: ×87%
    • Snow
      • Thin: ×76%
      • Medium: ×62%
      • Thick: ×52%

    Example[edit]

    Moving speed of a particular pawn can be calculated using the following formula:

    Move speed = (Base value + Offsets) × Factors × External factors
    

    Let us calculate how fast a human could possibly go. It would have the following values:

    Move speed = (4.6 c/s + 0.4 c/s + 0.4 c/s + 0.1 c/s) × (4.23 × 1.4) × 1 = 32.57 c/s
    
    1. Be aware that it is not possible to achieve this speed in a short time since the three hard drugs required to take have a 100% chance of causing a Minor Overdose and reducing Consciousness by 50%. 0.042 Overdose Severity is lost every hour so you would need to wait 1 to 6-hours between drugs.

    Notes[edit]

    Offsets, such as the speed decrease from gear or traits, occurs before multiplicative factors such as Moving. So while a normal human moves at 4.6c/s, and a human in a flak vest moves at 4.48c/s for a difference of -0.12c/s, a pawn with 2 archotech legs would move at 6.9c/s while the same pawn in a flak vest would move at 6.72c/s for a difference of -0.18c/s. Similarly, jogger-traited human moves at 5.00c/s for a difference of 0.40/s compared to baseline, but a pawn with 2 archotech legs would move at 6.9c/s while the same pawn as a jogger would move at 7.50c/s for a difference of +0.60c/s.
