Capturing bases, killing enemies, & destroying their equipment will give your character Battle Experience Points (BEP).  As you accumulate these BEPs your character will go up in Battle Rank.  As your character goes up in Battle Rank, you will earn Certification Points and Implant Slots.

• Certification points can be spent at Certification Terminals at the Sanctuary or at friendly Bio Labs to unlock access to various types of equipment, such as the Medical Applicator which allows you to heal injuries you or your friends may have suffered.  Certifications also unlock access to vehicles such as the Basilisk or AMS (Advanced Mobile Station).

• By spending your Certification points, this is how you will begin to specialize your character.  You could choose to go Heavy Assault and grab the tougher armors and bigger guns but then you might be dependent upon getting transported to the battle by others that have chosen to specialize in Piloting Vehicles.  Or you could choose to be an Advanced Combat Medic with the ability to revive fallen comrades on the field or an Advanced Hacker with the ability to quickly hack your way into an enemy base.  Or perhaps a smattering of all of the above?  In any case, the choices you make are not permanent as you may unlearn certifications and choose others in their place via the "Unlearn" feature in the certification terminal.
• Implant Slots are where cybernetic devices known as Implants are surgically implanted within your character.  These devices can endow you with super human abilities such as Surge, which allows for a brief but explosive burst of running speed or the Personal Shield implant, which when activated gives your character a temporary force field to protect them from damage.  Your character can earn up to a maximum amount of three Implant Slots but beware, Implants when activated, can quickly use up your stamina leaving you drained and unable to run.  Implants may be installed via Implant Terminals at the Sanctuary or friendly Bio Labs on any of the Battle Continents.
