Move Speed

Move Speed is a stat: Speed of movement in cells per second (c/s). Its default value is 3. A default Human has a base movement speed of 4.6 c/s.

Offsets

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

Traits
- Jogger: +0.4 c/s
- Fast walker: +0.2 c/s
- Slowpoke: −0.2 c/s
Gear
- Minigun: −0.25 c/s
- Plate armor: −0.8 c/s
- Flak vest: −0.12 c/s
- Flak pants: −0.12 c/s
- Flak jacket: −0.12 c/s
- Marine armor: −0.4 c/s
- Grenadier armor: −0.4 c/s
- Prestige marine armor: −0.4 c/s
- Cataphract armor: −0.8 c/s
- Phoenix armor: −0.8 c/s

Factors

The following factors are applied after the Offsets.

Moving capacity: 100% importance, no allowed defect. No Max (effectively 311%).
Go frenzy (inspiration): ×140%
Light: scaling linearly from ×80% at 0% light to ×100% at 30% light. Pawns that are Blind, have the Lighting: Darklight preferred precept, or have the Dark vision gene are unaffected by this factor.

External factors

Weather

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

Path cost

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.

Path cost	Move speed factor	Examples (random)
0	100%	Smooth stone, Column, Holding spot , Pen marker, Wall torch lamp, Bonsai tree , Wall lamp
1	93%	Straw matting, Burned floor, Rough-hewn stone

3	81%	Lichen-covered soil
4	76%
8	62%
10	56%	Egg box
12	52%
14	48%	Persona core, Chocolate, Yayo, Patchleather, Mechlink , Techprof subpersona core, Psytrainer , Jade, Healroot, Horseshoes pin... further results
20	39%	Slab bed , Slab double bed
24	35%	Blood torch
25	34%	Kneel sheet , Kneel pillow , Pew
30	30%	Toy box , Chess table, Meditation throne , Armchair, Passive cooler, Reliquary , Bryolux, Mech drop beacon , Grand meditation throne , Couch... further results
42	24%	Pine tree, Ancient bed , Wastepack atomizer , Table (3x3), Bamboo tree, Royal bed, Hospital bed, Vanometric power cell, Cypress tree, Saguaro cactus... further results
50	21%	Ancient mech gestator , School desk , Electric tailor bench, Auto inferno turret , Ancient equipment blocks , Ancient postbox , Ancient truck , Ancient tank trap , Ancient oven , Ancient mechanoid shell ... further results
60	18%	Ancient fence
80	14%	Fence

You can see the path cost of every thing here.

Flooring and terrain

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.

Flooring:

Floor	Move Speed Factor
Burned floor	0.93
Flesh	0.87
Fungal gravel	0.87
Gray surface	0.87
Rough stone	0.87
Rough-hewn stone	0.93
Straw matting	0.93

Other terrain
- Chest-deep moving water: ×24%
- Marsh, Shallow ocean water, Shallow water and Shallow moving water: ×30%
- Marshy soil, Mud, Soft sand and Ice: ×48%
- Sand: ×76%
- Lichen-covered soil: ×81%
- Soil, Stony soil, Rich soil: ×87%
Snow
- Thin: ×76%
- Medium: ×62%
- Thick: ×52%

Example

Speed of 29.61 c/s vs base speed of 4.6 c/s

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:

Base value: 4.6 c/s
Offsets:
- Jogger trait: +0.4 c/s
- Very fast runner gene : +0.4 c/s
- Naked speed gene unclothed : +0.1 c/s
Factors:
- Moving capacity: ×428% (see moving)^[1]
- Go frenzy inspiration: ×140%
External factor: ×100%

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

↑ 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

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.
