Putting an end to this before it gets all fucking drama-fied!
After seeing that there are no spoilers in the credits, I've gone to check. From the Main Menu, you click Credits, and then it comes up with 2 options, Staff (0) and Backers (X). After that, you can choose to enter your backer code (which I assume will take you straight to your name) but as we don't have them, I just skipped it. Can also confirm that my name is in there. I'm guessing the people who are saying they don't have it, either can't find it (the list is huge) or they have gone to the Staff section...or the end game credits shows the staff section first (which it should).
The list is fucking massive lol it's split up into sections of each Tier, and even then it took me age to find my name in the $500 pledge.
