I am playing Portal: Still Alive on XBox 360. In the challenge maps, there are advanced levels for chambers 13-18 named like "14: Advanced" and just like the standard chambers, they have medal challenges in least portals, fastest time, and least footsteps.

The targets for these challenges appear to be exactly the same targets as their standard counterparts. For example, the Testchamber 13 least portals challenge gives bronze at 9 portals, silver at 5, and gold at 4. 13: Advanced also has bronze at 9 portals, silver at 5, and (presumably) gold at 4 even though the chamber is modified.

Also, from what I can gather online, the Orange Box version of the same game didn't have medal challenges for the advanced chambers at all (and still had the same medal challenges for the standard chambers).

These facts cause me to believe that the appearance of medal challenges for 13-18 advanced chambers was merely a oversight in the Portal: Still Alive version of the game.

Are these medal challenges impossible as I suspect?

    How in the world do you expect us to know if something was intended or not? Mind reading?

    @kotekzot Developer interviews or commentary elsewhere that indicate one way or the other? Who knows, but just so: somebody might know. Asking is a way of finding out if anyone knows. Jan 28, 2013 at 16:28
  • @kotekzot Often game developers are not extremely secretive about the development of a game. In Portal: Still Alive there is commentary built into the game that tells about the how the 2-portal solution for Testchamber 13 was left in after a playtester discovered it. I assume advanced medal challenges were unintentional, but I don't know. Someone else might know. What's the harm in asking?

  • Seems like the greater internet doesn't know based on 16: Advanced is impossible and another for the same. However, 17: Advanced is possible

If they would be impossible they won't be created.

Search up for speed runners, they know how to do this. Just if you want to learn how to speed run, but it is to hard. Like they use bugs, and other stuff. But now more about your question.

They are just hard to beat and you have to think for a long time.

If they would be impossible they won't be created.

Here's Advanced Test Chamber 13, for example, in spoilers:

    Generally, we prefer answers to answer the question directly. Yeah, they're not impossible, but that information isn't really useful if you don't go more in depth on how to go about accomplishing it.

    We don't care about spoilers here when it comes to answering the question. Directly answer the question, please. Telling someone to search for speedrunners isn't very useful, either. At the very least, linking one of the videos of the levels the asker is having trouble with would be good.

    We expect quality here at Arqade. If you show effort in your posts, you'll do fine. If you don't like criticism, well, this isn't the place for you, then. One thing that might help is to ensure your post has all the info you want it to before posting. Quality over quantity.

    - Telling people to search for an answer is not a good answer on a Q&A site. In those cases where lmgtfy.com is the proper answer, consider using the "close" vote. - Saying impossible achievements won't ever be created is clearly a false assumption.
