It’s a holiday tradition! We’ve decorated a Christmas Tree in the GOG.com office. Random people are running around in holiday hats and singing along the winners of the Holiday Songs Contest.

We think that our website deserves some holiday touch of its own and we will deliver that! During our 50% off Xmas Sale we already had four big publishers join forces with us. EA helped us with the the EA Crossword Puzzle, Interplay in the Interplay Caption Contest, thanks to Activision for the Activision Holiday Song Contest and last but not least Ubisoft motivated you guys to write some Ubisoft themed New Year’s Eve Resolutions.

So it’s finally time for the Third Annual GOG.com Screenshot Scavenger Hunt to start! Here are the rules: From now until Friday the 30th of December 2011 we’re going to have some Holiday themed screenshots up on our website for you to find. ;) They will be hidden in our game cards, surrounded by all of the regular screenshots. The trick is (as you can see below) that some of them will be “spiced up” with some holiday themed devices:

When you find a holiday themed screenshot (there are 20 of them in total), be sure to write down the name of the game. When you’ve got them all, list them all in an email to "[url=mailto:contest@gog.com?subject=GOG.com 2011 Scavenger Screenshot Hunt]contest@gog.com[/url]" with the subject line being "[url=mailto:contest@gog.com?subject=GOG.com 2011 Scavenger Screenshot Hunt]GOG.com 2011 Scavenger Screenshot Hunt[/url]". From every valid application we will pick 10 winners who got all the games right and gift them two games from the entire catalogue (excluding The Witcher 2). The contest ends on Friday December 30th 2011 11:59 GMT

Can you post the correct ones? Can we discuss them now?

So about this vulnerability, or how to break GOG's contest in five easy steps if you have at least very basic knowledge of HTML and a few standard software tools, no fancy scripting required:

1. Open the catalogue. Mass download all of the product pages (i.e. 1nsane.htm, advent_rising.htm etc.) using a suitable tool, like Opera's Links sidebar, Firefox's DownThemAll extension, wget, whatever, to a folder on your disk.

2. Open any file from the 340 you just downloaded and find the image gallery code in the HTML (shortcut: search for "click on a thumbnail to enlarge the screenshot". Notice that GOG's automated image upload system stores everyting neatly sorted in "static.gog.com/upload/images/YEAR/MONTH/". See the exploit now?

3. Now we need to search the content of the files for the string "upload/images/2011/12/"; this way, we get all product pages featuring images that were uploaded in December. Good news is that there was no new release in December, bad news is that some of the game box art was updated, so there will be quite a few false positives (the main culprit here is the "Customers who bought this game also bought:" section). This can be done using standard Windows search, but if it is acting up (not unusual, in my experience), Total Commander or one of its cousins will do nicely. (In TC, go "Commands > Search > Find text" in the folder with the .htm files.)

4. I got 53 entries. Not a great result (last year the same procedure got you to about 25, I believe), but much more manageable than 340. From here, you can either dig through the HTML to root them out manually, or just look at them. It shouldn't take you very long to find all 20 now.

5. Send in your answers, cheater.

(I did not participate this year. I thought it kind of pointless, considering this glaring exploit still wasn't fixed, for example by simply replacing the screenshots directly in their original folder instead of uploading new ones. And I'm posting this because I don't think the current state of things is fair, that's all.)

If, instead of searching for "images/2011/12/", you search for "\/images\/2011\/12.*screenshot" (assuming you have a tool that supports regular expressions, e.g. grep) you get only 22 results -- the 20 modified games + the 2 games published in December (Desperados 2 and Gothic 3).

babark: Can you post the correct ones? Can we discuss them now?
Here is my solution, based on the "vulnerability":
1) Age of Wonders 2: The Wizard's Throne
2) Apache vs. Havoc
3) ArmA Gold Edition
4) Atlantis: The Lost Tales
5) Broken Sword 4: The Angel of Death ( Secrets of the Ark )
6) Crusader: No Regret™
7) Dungeons & Dragons: Dragonshard
8) Gangland
9) Little Big Adventure 2 (Twinsen's Odyssey)
10) Might and Magic® 8: Day of the Destroyer™
11) Normality
12) Populous™
13) Rayman 2: The Great Escape
14) Redneck Rampage Collection
15) Restaurant Empire
16) Serious Sam: The Second Encounter
17) Spellforce 2: Dragon Storm
18) Ultima™ 4+5+6
19) Witcher: Enhanced Edition, The
20) XIII

The one I found most difficult is "XIII",

Yeah, I assumed there would be a better way, but I wanted to show the most primitive corner-cutting method, available to pretty much anyone. I haven't bothered to hunt for the screenshots myself, to be honest, I just tested if the method still works.

EDIT: So TotalCommander apparently does support regexp in searches. That's good to know. But still, that is a bit too much to ask from an average user.

Now that its over let's have a show of hands...

Who had trouble with the screen shots for Chaser, Tyrian 2000 and XIII?

Who was thown off by the holiday items being put in a similar color scheme to the original game, such as Santa viewd through a Night Vision scope or a Sepia Tone Santa hat or that one where the Santa hat used the marbled red from the characters armor?

Who carefully read through all the dialouge in Zork just in case GOG decided to add Christmassy words as part of the contest?

Stevedog13: Now that its over let's have a show of hands...

Since I used the "vulnerability", I didn't have trouble with the ones that weren't actually modified (Chaser, Tyrian). But XIII was so difficult for me that I started thinking the "vulnerability" wasn't working after all.

Ok so i got them right after hard work not using screenshot dates so Murphy's Laws say that i;m not going to win. Fun contest though. :)
Posted December 30, 2011
Chaser was easy to dismiss because that snowman is behind the gun and it fits the rest of the shot too well. Now, the snowman in Cannon Fodder...I had to look that up.

Atlantis The Lost Tales is the funniest one, I think.

I'm just gonna go ahead and shoot myself in the head...

I used the regular tedious method, looking through all the pictures, and when I found one, I copied the game's name in a separate text file.

In the text file I had 19 game titles after 2 hours.
I gave up, "it does not worth it, i'm not gonna waste another 2 hours on this, to hell with this stupid contest".

It turns out I found all the pictures. Just somehow made a mistake of not copying one game name to the text file after finding the picture...

this is even more frustrating than simply not finding the 20th...

reading this topic, halfway I realised the exploit, but only 10 minutes before the contest ended, so it was too late by then to use this method for finding (again) the 20th game...

This was a very hard contest. I've found 18 pictures using the "traditional" method (clicking on every picture at the games' pages).
I still don't know which picture was modified at ARMA: Gold Edition, because I remember I looked it's pictures, too, but I didn't found anything that would be modified by the GOG Team.

Second set of thumbnails, centre of bottom row. The green scope.

For me, the image from Spellforce 2 was the most hidden of all. Hell, I was looking at the "helmet" all the time, and still was thinking that it was a normal helmet. At the end I found it, but it took me THREE entire catalogue-check to notice it.

Winners have been contacted via e-mail.
Check your inboxes ;)

All the Xmas themed pictures are gonna be posted on our Facebook profile in a sec.
