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.

Here are some specifics for X-COM soldiers (multiply by two to get TUs):

• 2 pts - Walking 1 adjacent tile (little or no grass)
• 3 pts - Walking 1 diagonal tile (little or no grass)
• 3 pts - Walking 1 adjacent tile (wheat field)
• 3 pts - Crossing broken house wall
• 4 pts - Crossing UFO Door
• 4 pts - Walking up/on Ramp/Hill/Dune (Not the first 'outer edge' of hills and dunes, but the next, higher part. Hills and dunes continue to need 4 even once on the flat top of them.)
• 5 pts - Crossing adjacent broken barn wall
• 6 pts - Crossing house door
• 6 pts - Using stairs

Also: Walking up an Avenger ramp uses 3 per tile, whereas walking down uses 3 from tile 1 to 2, and then 4 from tile 2 to 3!!

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)
