Ok so I've beaten the game blah blah all that crap. I got the extra stuff in the Leech Hunter (Magnum and Infi Ammo) and beat the game again, thinking I'd get the Rocket Launcher (I beat it in under 3 hours), but the STUPID THING WAS ON EASY!!!! BIG TIME

!!!
Here's my question: Is there ANYWAY in the 9 5/8th layer of Hades that I could somehow keep what all I've done on the saved portion of my game, but up the difficulty level? I've tried Continue and Restart, but to no avail. I can't seem to change the level. I don't want to have to beat the game AGAIN and the Leech Hunter twice AGAIN just to be able to get the Launcher. Anyone have a glimmer of hope?
