Internet Explorer is shit.

Standard rules apply. Do not leak, post answers, suggest hints, or directly link to the prize/giveaway.

You start here. Good luck.

Hint It's just like my quiz says, translator site is useless for this puzzle. It might give you a hint on what to do with the code, but that's all. Don't waste your time there.

Hint When you meet a fair lass, be sure to check her out properly.

Hint If you got a drawing, it is a copy. You need to find original one.

Hint Familiarizing yourself with how sites like pastebin or imgur actually work can go a long way when it comes to solving puzzles.

Solution

1. Supreme Commander 2 giveaway description is of course an itstoohard code = http://itstoohard.com/puzzle/e1uuLD1Y

2. After answering the quiz question you get a pastebin link

3. Pastebin code is an image encoded to base64. If you tried to decode it on the translator page, you might have noticed it says 'GIF89a' at the beginning. What's the easiest way to make an actual image out of it? First, tweak the pastebin url a bit to get a non-raw version. As you can see, this paste has a previous version. Click view the difference.
   Now just put both versions together, paste the whole code into your browsers address bar and press enter. Clicky

4. Those of you who recognized the drawing probably knew where to look, but you can just save the image to your hard drive and upload it to Google Image Search. Either way you should end up here.

5. Open the Imgur link under Q3 and delete .png file extnsion from the url. Clicky. URL from the image description will take you to the next step.

6. When you decode the morse code you get just a short message. Dead end? Nope. Download the .mp3 and view it's ID3 tag with your favorite audio player or just open the file with a notepad. YouTube link I put there should be hard to miss. Clicky

7. It is a short gameplay video of Sherlock Holmes versus Jack the Ripper. I tried to hint at the next step by taking about 15 screenshots and browsing them near the end of the clip.

8. If you check my Steam profile, you'll see I have only one Sherlock screenshot posted there. Click the link in comments below to see an almost identical image. Take a close look to see that pretty lady has a giveaway code tattooed on her right arm.
