Overview
You’re a new player and you don’t know what are those post-it? No problem, i’m here to help you : )
Completion Mark Rebirth
So these are the 6 originals:
As you can there’s 2 colors, white and red, white is when you do it in normal mode, red is when you do in hard mode.
Hard mode isn’t that difficult, you don’t get many drops, and there’s more champions, but other then that it’s like normal gameplay.
Completion Mark Afterbirth
Now what you have all been waiting for, The afterbirth Marks.
With Afterbirth released yesterday they added 3 more completion marks, so if you don’t want spoilers STOP READING THIS NOW.
Hush:
Like the previous marks, there normal and hard mode variants (So far I only have the hard mode image), and to get this one you need to beat Mom’s Heart/It Lives in under 30 minutes, when you do a door will open and you will face Hush (tough boss).
Ultra Greed:
To get this one you need to face Ultra Greed on Greed Mode, again is tough boss.
Mega-Satan:
To face Mega-Satan you need Key Piece 1 and Key Piece 2 or Dad’s Key.
Don’t forget, defeating each boss with different characters will give you different items.
