Respirator Implant (EU2012)
We can fabricate a module that will automatically detect chemical and physical threats to a soldier's oxygen supply, and deploy uncomfortable but potentially life-saving oxygen tube shunts in a matter of seconds. This module will fit all of XCOM's armor designs.

- After Titan Armor is developed and deployed, this device is still useful with Psi armors. Even with Titan Armor you may want to bring it for the extra 2 Health Points it provides.
- Thus, they supersede Nanofiber Vests in utility. Particularly on harder difficulties, it may be more cost-effective (and quicker) to skip vests and go for the Implant first, especially in light of Seekers being able to sneak attack past the starting armor's +1 health, putting your soldiers into recovery time, and the many Thin Men you'll be facing (and be at risk of poisoning from) for a while.
