Infinite Shields/Energy (rail stages): 1 instance
NOTE: Take a hit early and the shields (@ upper right) will auto fill after that but it takes about a minute. If playing without the Invulnerability hack, avoid more damage until they're full which will then keep Energy (@ upper left) from dropping below normal, save for a brief instance when hit.
