Scientists where building a robot that can transform into weapons.They called this the Sentinal project.The sentinal project was a key military advantage for the United Alliance.But some of the robots didn’t turn out so good, the scientist forgot to add a fusion core(a key component the robots need) into them that help transform to any weapons they want.They didn’t know there was a virus in one of the robot’s later on when they start to build the new robot called Zen, they knew that he can’t transform by himself. He has a fusion core so they made Evan, who was his partner who can transform to any weapon that Zen want’s. Zen start to get out of control as the virus take over his system now Evan has to find a way to destroyed the virus. But Evan has no weapons, so Evan has to find a fusion core that can help him transform to any weapon that he want’s along the way Evan finds old robots and heal them. As he is healing them he is also scanning them to see what weapon they are.
