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?
EDIT: I care more about whether the medal challenges were intended than impossible. I am aware that gamers can often find ways to perform unintended shortcuts and therefore it might be easier to answer "are they intended?" than "are they impossible?"
