When playing hard mode I noticed that some energy tanks are missing when playing. Is this all of the tanks and will I be stuck on three health all the way though the game or is it only some of the tanks that are removed? Are there any other power ups that are removed in hard mode?
In hard mode all life capsules but one have been removed, all chests containing missiles have been removed, the chest containing super missiles can't be opened, and the sisters don't appear.
I'll edit again if I can find some better sources.
