Implants are a way to make your Crew even more useful. Each crew member can have up to three Implants, but can never have the same Implant more than once. Therefore, a ship may benefit from one specific implant up to five times. Each implant slot has a color and may only take an implant with a matching color (red: Attack, blue: Defense, yellow: Utility). However, each time an officer reaches sufficient Experience to level up, one of their slots (from left to right) will turn into a golden Chroma slot and be able to take an implant of any type.
There are some stats (ie. Missile Range and Hull Strength) implants provide which no crew members has. On the other hand, Energy Efficiency is the only stat a crew member offers for which there is no implant. If a certain stat is provided by both, the bonus from the best crew member(s) for that stat is as high as the bonus from equipping the corresponding implant five times.
