This article details how movement works under the hood in Underrail.
Basics
At its core, Underrail's game engine is real-time with smooth movement. This is converted into discrete square map tiles and combat turns for gameplay purposes.
- One turn equals 5 seconds
- Moving the distance of one tile costs 10 MP
- The unmodified movement speed equals 135 MP
Distances are calculated as two-dimensional Euclidean distances (also known as Pythagorean distances) and movement point costs are rounded up to integer.
- Example: Moving one tile diagonally costs 15 MP, moving 10 tiles diagonally costs 142 MP. (Rounded up from 14.1421356237 and 141.421356237 respectively.)
Items and effects that modify movement speed or movement points usually modify both. These values are not automatically converted, they're manually defined on each source of movement modifiers, so they're not necessarily completely consistent.
Real-time
All movement speed modifiers stack additively, except Stealth Mode penalty, which is multiplicative with the others.
Agility, MP/AP, Armor Penalty, etc. have no effect on movement speed.

| Interloper | Reduces Stealth Mode movement speed penalty to 30% | allows retaining of some movement points after Stealth Mode | |
| Sprint | Increases movement speed by 45% | ||
| Strider E | Increases movement speed by 15% | ||

| Stealth Mode | Reduces movement speed by 45% | Stacks multiplicatively with other movement speed modifiers | |
| Chilled | Decreases movement speed by 12% per stack | 12% is approximate. Might be 12.5% or 1/8Verify | |
| Fatigue | Decreases movement speed by 20% | ||
| Slowed (Sticky Oil) | Decreases movement speed by 20-69% | ||
| Slowed (Web) | Decreases movement speed by 50% | ||
| Lightly Encumbered | Decreases movement speed by up to 50% | ||
| Heavily Encumbered | Decreases movement speed by up to 70% | ||
| Completely Encumbered | Decreases movement speed by 100% | Prevents all movement | |
Turn-based
- This section needs expansion with list of MP sources.
- Character base Movement Points equal 30 + extra 3 points for every point in agility above 5. Movement points can only be used for moving.
- Movement points are affected by agility, armor penalty or bonus, encumberance and some feats.
- Most effects that change movement points also change real-time movement speed.
- Some creatures, such dogs and spawn, have natural bonus to movement points.
Vehicle mechanics
- This section needs expansion with Jet Ski stuff.
