Rebelstar: Tactical Command

In the year 2117, a race of aliens known as the Arelians have enslaved the human population of Earth using their henchmen, the savage Zorn. They insert implants into infants' brains at birth, to be able to track them. As soon as someone turns 30, the aliens take the person away and nothing is known about their subsequent fate. The main character, Jorel, after losing both his parents to the alien invaders, decides to flee south to Mexico to join the rebel forces and fight the alien invaders. Thanks to his strong psionic resistance, his brain rejected the implant and he brings new hope to the desperate human race looking for a leader.
