Beating Dread in a certain amount of time will allow you to unlock artwork in your gallery. The artwork goes through the entire series. Here’s how to unlock them:
- Metroid Zero Mission: Normal mode, 8+ Hours
- Metroid Samus Returns: Normal mode, 4 – 8 Hours
- Super Metroid: Normal mode, < 4 Hours
- Metroid Other M: Hard mode, 8+ Hours
- Metroid Fusion: Hard mode, 4 – 8 Hours
- Metroid Dread: Hard mode, < 4 Hours
If you beat it under a certain time you will get all the other ones above that time. For example, if I played the game on normal and beat it in under 8 hours, I’d unlock both the Samus Returns image and the Zero Mission image. They are game mode specific though.
Acquiring 100% of the items will unlock all of the images in the Chozo Archives gallery.
After unlocking all of the images, you will unlock a final “completion” image which shows a large selection of all the characters from the series (non-Prime) history. There are two of these, one has suited Samus and one has Zero Suit Samus.
Of course we’ll host these images on the site once we can get clean, high-res, watermark-free copies. Stay tuned.
In other news, the Dread Special Edition artbook will eventually be scanned and made available on our site. We’ll let you know when that happens.
