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.

Factors[edit]

Offsets[edit]

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
- Prestige cataphract armor: −0.8 c/s

  - Unclothed: +0.1 c/s
  - Clothed: −0.2 c/s

Factors[edit]

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[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.

Path cost	Move speed factor	Examples (random)
0	100%	Wall torch lamp, Wall lamp, Bonsai tree , Column, Pen marker
1	93%	Burned floor, Straw matting
2	87%	Gray surface , Flesh
3	81%
4	76%
8	62%
10	56%	Egg box
12	52%
14	48%	Potato plant, Jade, Lightleather, Bluefur, Horseshoes pin, Resurrector mech serum, Incendiary shell, Wolfskin, Psytrainer , Gene processor ... further results
20	39%	Slab bed , Slab double bed
24	35%	Blood torch
25	34%	Pew , Kneel sheet , Kneel pillow
30	30%	Giant rafflesia, Armchair, Mech drop beacon , Stool, Reliquary , Firefoam popper, Toy box , Berry bush, Hydroponics basin, Bryolux... further results
42	24%	Mech booster , Palm tree, Table (2x2), Ancient lamppost, Poker table, Billiards table, Birch tree, Chokevine, Tube television, Harbinger tree ... further results
50	21%	Ancient refrigerator , Ancient giant wheel , Brewery, Hand tailor bench, Ancient mechanoid shell , Shard inhibitor , Ancient long crate , Ancient pipes , Shelf, Ancient large crate ... further results
60	18%	Ancient fence
80	14%	Fence

You can see the path cost of every thing here.

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.

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[edit]

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: ×423% (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[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.
