Worm War I for Atari 2600
in this game you play as a tank moving vertically destroying worms and other objects in your way however you have limited energy every time you get hit or speed up you lose energy. the biggest downside to this game is the energy limit I didn't not find a way to replenish it I don't know if there even is a way to otherwise it wasn't bad not as good as centipede or millipede.
