12. Heart Tanks – Mega Man X (1993)
Blasting away baddies in the 22nd century could do damage on the body. Luckily for X, your trusted Maverick Hunter throughout the Mega Man X experience, there were a few Heart Tanks that could be picked up along the way. Although it only upgraded your maximum health by 2, the results were definitely worth it when you were going up against Chill Penguin or Flame Mammoth.
