Money, items, skills, upgrades, etc. iirc. Money being the big one.
Money in Bayonetta is meaningless once you can do the Bracelet of Time + Kilgore glitch trick. Look it up on Youtube.
If you ever have to start a new Bayonetta file, all you have to do to obtain most of the unlockables is:
1. Complete the game on Normal, collecting all weapons along the way.
2.
Farm 3 million halos and enter the
Bracelet of Time code.
3. Use the Bracelet to farm enough halos to enter the rest of the codes and purchase everything from the store.
Then to get the rest of the things...
4. Complete the game on Easy to unlock the Eternal Marionette accessory (i.e. auto mode).
5. Complete the game on Hard to unlock Non-Stop Infinite Climax difficulty.
6. Complete 100 chapters total to unlock the Sai Fung weapon. (The Prologue in the graveyard is the shortest.)
(For an easier time, use the
lollipop cutscene trick to start off invincible in most boss battles, and abuse the hell out of yellow lollipops.)
You can probably do all of this in under 15 hours if you're really efficient. It's not that hard if you enjoy the game. And you can always use the Kilgore glitch if you want to get through the unlocking process as quickly as possible.
Dat space harrier before Jeanne tho :/
My favorite boss yet I rarely fight her because of that.
Yeah, one of the game's biggest flaws is locking one of its best bosses behind a tedious vehicle segment. Bayonetta 2 is way better in that regard. You can replay the entire story front to back and have a much more consistent experience.
