Vectron (INTELLIVISION INTEL)

Vectron's goal is to build an energy base, section by section. You add each section by moving your energy block into place and filling it with an energy blast. You must protect your energy block against Hungrees, G-spheres, splits, sweeps and prizums which can destroy it. Take them down with energy blasts or neutralize them with the special energy of an E-Pak. Don't run out of energy or you lose an energy block. There are three energy blocks per game. When they are gone, the game is over.
