DO NOT POST ANSWERS! YOU MUST FIGURE OUT THE URL TO THE PRIVATE GIVEAWAY!

48h giveway to allow enough people to join in.

the URL scheme is like so: http://www.steamgifts.com/giveaway/XXxXX

The below numbered hints/descriptions are for each letter/number represented by X or x.
X = uppercase or number.
x = lowercase.

There is only one number (not third one) and any involving a letter is the first letter only. There are three characters that the answer is directly a letter! 1 number, 3 letters, 1 first letter of first word. Uppercase/lowercase of the hint answer is irrelevant. If there is a difference, follow the URL scheme.

1. ZQNkZQRkZGNjZQRjZGRkZQNjZGNkZGNkZQNkZQRkZGN= (it uses 4 encryptions/encodings)
2. At top, round, yellow, gaming-related (sorry to Sony-only snobs =P)
3. 96.5% more wub wub and 870 gajillion more guns
4. Rainbow ___
5. Canceled TV show ~1 year ago.

If you need an extra hint for the first character, then here you go.
