Implant
Implants are upgrades that you apply to your character that improve your performance in combat in various ways. Each faction offers a different implant at each rank, provided you have enough reputation with them. You can only choose one implant at each rank, but if you change your mind you can change the implant for a fee of 100,000 credits per implant, or 950,000 credits for full reimplantation.
Implants only take effect when flying a ship of the same rank or higher, so a rank 3 implant will work on a rank 3 ship or higher, but will not work on a rank 1 or 2 ship.
