Gene Mods (Long War)

Gene mods work similarly to how they work in vanilla, though the set of available mods is different. Please note the following:

Secondary heart does not protect the Volunteer from mortal wounds. A fatal shot will kill him/her instead of triggering the perk. This behavior only pertains to the final mission, it is a vanilla mechanic.
Neural Damping is unavailable to Psi-trained troops.

Adaptive Bone Marrow	Legs	Chryssalid Autopsy	§30, 15	Wound recovery time is reduced by 66%. Soldier regenerates 2 HP per turn up to the HP max without armor. Imposes +9 hours fatigue.

Gene mods are relatively cheap for their benefit, both in terms of cash and, to a lesser extent, Meld, but bear in mind that because you need to swap out soldiers on missions due to fatigue, you'll get less benefit from each gene mod than you would in vanilla.
