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.

Gene mods

Name	Slot	Prerequisite	Cost	Description
Neural Damping	Brain	Berserker Autopsy	§20, 15	Confers immunity to panic and all mind affecting psionic attacks. Neural damped soldiers cannot learn psionic skills and psionic soldiers cannot be neural damped. Imposes +6 hours fatigue.
Smart Macrophages	Brain	Sectoid Autopsy	§15, 8	Confers immunity to acid, and medikits and restorative mist heal +2 on this soldier. Imposes +3 hours fatigue.
Hyper-reactive Pupils	Eyes	Xenogenetics	§10, 4	Confers +10 Aim to any shot after a miss. Imposes +3 hours fatigue.
Depth Perception	Eyes	Xenogenetics	§10, 4	Height Advantage confers an additional +5 Aim and +5 critical chance. Imposes +3 hours fatigue.
Secondary Heart	Chest	Muton Elite Autopsy	§50, 15	Causes soldiers to bleed out instead of dying the first time they go to zero health during a mission. The bleed out timer is extended for 2 turns. Prevents loss of will from critical wounds. Imposes +6 hours fatigue.
Adrenal Neurosympathy	Chest	Muton Autopsy	§20, 10	Overloads the soldiers adrenal glands: when a kill is confirmed the soldier emits pheromones that grant offensive benefits to all nearby squad mates. Imposes +9 hours fatigue.
Bioelectric Skin	Skin	Seeker Autopsy	§25 ,10	The soldier projects an electric field from his or her skin, revealing but not alerting nearby enemies, and is immune to strangulation. Imposes +6 hours fatigue.
Iron Skin	Skin	Cyberdisc Autopsy	§20, 10	Confers 1.0 damage reduction. Imposes +12 hours fatigue.
Muscle-fiber Density	Legs	Thin Man Autopsy	§20, 12	Confers superhuman leg strength, enabling the soldier to reach high positions without the need for ladders or other climbing aids. Imposes +9 hours fatigue.
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.[Verify?] 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.
