This is a full play from the beginning to the end on Hardcore mode.
This means no continues and damage is tripled. You also do not get health back after every stage , only at the end of every mission after defeating the level boss.
I use a lot of tricks and shortcuts as well as collect all extra lives to make this as easy as possible.
I also show the easiest boss strategies I know of.Also you can push start and choose to restart the mission retaining all lives you had at that point. So to make it easy on yourself when you lose too many lives push start and restart the mission until you happy to continue.
