You'll eventually unlock pistol dual wielding, charged shots, and quicker reloading for Bishop and dual swords and
a fun telekinetic ability for Saija, while Boss has a bionic arm, and Elder receives multi arrows, to name a few of the abilities on offer to the noble hackers.
Carter himself has the ability to summon enemy units and use psychic powers, the most
fun of which is the
telekinetic lift which brings back fond memories of the gravity gun from Half Life 2.
