Energy
Energy, or stamina, refers to your soldier's abiity to endure intense power walking over several turns. Energy is only spent when a soldier walks. No other action uses energy. More energy and time units are spent depending on the difficulty of the terrain traversed.
Usage
Energy Units, or EUs, are only depleted when walking. For X-COM soldiers, they are used at half the rate of TUs. The actual formula relies on a unitref stat: unitref[45].
Formula: Energy Used = INT(TUs Used / 2^unitref[45])
Example: All X-COM units have a unitref[45]=1. Crossing a standard tile to an adjacent one uses 4 TUs. This means that they will use up, INT(4 / 2^1) = 2 EUs.
Fatal Wounds
Each fatal wound to the body reduces the soldier's energy by 10%.
Recovery
A soldier's ability to recover energy is determined by the soldier's base (initial) Time Units. Thus, their raw recruit TU value dictates this throughout their career. You can see initial TUs on the Soldier tab (Strategic view) as the darker part of the TU bar.
Energy can also be recovered by way of stimulants from a Medi-Kit.
Formula: Energy Recovery = INT(Base TUs/3)
| Time Units | Energy Recovery |
|---|---|
| 50 | 16 |
| 51 → 53 | 17 |
| 54 → 56 | 18 |
| 57 → 59 | 19 |
| 60 | 20 |
