Circulatory System: Cyberpunk 2077 Cyberware

Game: Cyberpunk 2077
Content Type: Gaming Guides

Circulatory System implants deal with Stamina and Health restoration and preservation (quite useful for melee and other close-range combat), but can occasionally include such enhancements as reducing Cyberware-related cooldowns and the Breach time increase for the Breach Protocol. There is a potential for something interesting in this section for the majority of builds.

Keep in mind that Cyberware that improves on Health and Stamina in this section — especially on higher rarity ranks — requires points in the Body Attribute. There are also a few nice treats for Tech Ability builds in this list.

Do I Need Circulatory System Cyberware?

There is something in this section that can be used by the majority of builds: there are plenty of sustain abilities for Body Attribute for stamina and health, as well as the valuable Cyberware cooldown reduction for Body Attribute builds (pairs great with Circulatory, Nervous System, and non-Cyberdeck Operating System Cyberware).

For Technical Ability builds, there are ways to deal AoE damage or restore health by discharging a weapon.

Without any Intelligence Requirements needed and for a low price, Netrunner builds can pick up a Tyrosine Injector to increase Breach Protocol time by 100%. Uncommon grade and low price might look unappealign at first, but the 100% time increase is on par with highest level Skill Progression Rewards for the skill or the level 20 trait Perk, so don’t write it off just yet.

Note: all items are listed with a range of minimum to maximum values.
Beware that there is a significant value variation due to rarity. Starting and highest rarity rank is likewise listed as a range in parenthesis. Most of the cyberware comes across all rarity ranks. We will not be listing intermediary values to keep things clean.
