Preorder bonus

[rarutero]

So is there anything you exclusively get by pre ordering? or can you unlock all of it later by playing?

[Xaelon]

Nope. It just gets you instant access to stuff you can unlock by playing the game normally.

Here's what the store page says about the preorder bonus:

  Pre-order now to receive the following bonus content:
MELANDER C3 G13 Special Customization “TENDERFOOT”
• MELANDER C3 parts set (early unlock)
• Emblem (early unlock)
• Exclusive AC Decal
* Early Unlock: The parts set and the emblem can also be obtained by progressing through the game.

The bit you care about is at the end there.

[Taran Tatsuuchi]

The only part that isn't specified as an early unlock is the decal.
