This is a giveaway for the Hitman Collection, including :

Hitman: Codename 47
Hitman 2: Silent Assassin
Hitman: Blood Money
Hitman: Absolution
Hitman: Sniper Challenge

If you don't own MORE THAN TWO of those games you're welcome to participate. You must be at least level 2 and have a profile in good standing (no unactivated gifts, no gift won twice, no VAC ban). The giveaway ends in a week.

You can start here

It is hard, but it's not broken, so disregard people stating that they found a link that "doesn't work".

HINT : Many people seem to have a problem with my handwriting. Fair enough, if you find what you are supposed to find there's no reason to get stuck just because I write like shit. So, here's the format for that thing you found but couldn't figure out :

lowercase letter, lowercase letter, number, lowercase letter, number.

HINT 2 : For the part that is not handwritten... Be careful with the font. It makes everything look like it's uppercase.

HINT 3 : An user who just solved the puzzle warned me about something : when you get to the second dropbox image, DO NOT SAVE IT by right-clicking it. Instead, use the dedicated button in the dropbox interface.

That should be enough.

SOLUTIONS

1) A puzzle about bald guys :
1 - John Travolta
2 - Patrick Stewart
3 - Verne Troyer
4 - Barbie
5 - Britney Spears

Answering correctly gives you this link

2) First dropbox image :
If you look carefully at the image, you might notice in the upper-left corner, some text hidden in the HUD : i.imgur.com/fgL5wVH.jpg

3) Imgur image :
If you look carefully at the image, you will probably find letters hidden in the background. They are - obviously - upside down, so just twist your head at 180°, ouch, and you'll see the letters are ef1t6.

You know what do do with 5 characters codes if you are, let's say, a steamgifts user : www.steamgifts.com/giveaway/ef1t6/

4) Hitman Absolution giveaway :
Wait, what, this giveaway ended a year ago ! But a message tells you you are in the right place. Up until now my puzzle was about pictures, so it's safe to assume it's the same on this step. Just have a look at the image posted on the giveaway and you might notice these words : "reserved for bumps".

When I created this thread I made a "reserved for bumps" post, at the top of the page (or at the bottom if you're using an addon for SG). There is a super duper secret url hidden in this post. Just look at the source code to find it : https://www.dropbox.com/s/g7euyuhu1a6nddo/01.jpg?dl=0

5) Second dropbox image
If you've spent too much time on this picture I'm certain your face started looking like the one in it. Sorry about that, some people like it challenging and I had to change my method a bit.

There's a reason why this picture is not hosted on a "regular" image hosting site. Putting it on such sites will slightly modify it and strip it from informations that might have been hidden, for instance, secret text written in the data of the image. Download the image and open it with a text editor. At the end of the code, I added an url : www.itstoohard.com/puzzle/gO9ZfQFx

6) Second itstoohard puzzle :
1 - 640509-040147
2 - 5
3 - Merces letifer
4 - romania
5 - WA2000
6 - silverballer
7 - rubber duck
8 - smith

Variations of the format for the answers were included, so that you could still get it right if you wrote "5 fathers", "five", or "five fathers" for instance.

Solving this itstoohard puzzle gives you an url : http://www.sgtools.info/giveaways/b8233484-ec42-11e5-8d20-04019cc0dc01

7) Final dick move :

However, if you just click the link, it takes you to a DiRT showdown giveaway of mine that ended a while ago. Instead of clicking the url you've been given upon completing the itstoohard puzzle, Just copy the url and paste it in your browser, it will take you to the correct giveaway.

I hope you had fun working on it, please let me know, feedback is always useful.
