Dark Plateau

Dark Plateau was a place made by Gamer3D on December 18th, 2008. It is a desert place with rock formations set on a night sky, but there's a hidden lab under the large rock formation, with puzzles and stealth required to obtain a badge.

The owner planned to make a hat for when the player got the badge, however scrapped it. His account seems to have been terminated as well, possibly due to password sniping.

Walkthrough

 * 1) Go under the arch shown in the thumbnail. It is a vaguely mushroom shaped.
 * 2) There is a small rock underneath the arch. Clicking it will reveal an elavator the player takes.
 * 3) Once you've reached the bottom, a door will open revealing a lab area. There will be three areas.
 * 4) Go to the area on the left first, and enter in code "83538" to enable the middle area. It may be a bit tricky to solve the water puzzle.
 * 5) Go to the middle area and the keypad in front of you, enter code "23678". This would be the same code you would get if you solved the puzzle on the right area. Again, it is a tricky puzzle.
 * 6) Go into the area behind the door you just unlocked, take another right, and you should see another door. It has a checkpoint so don't be afraid to die.
 * 7) Jump into the area with crates: Several moving camera things will kill you, so watch out.
 * 8) Go through the area with crates, you'll see a small entrance to a second crate room, click the button to open the door.
 * 9) Go into the last area with crates, and locate the middle stack. Push one of the crates in to reveal the location of the googles for the badge. This appears to be the only glitchy portion of the game.

Broken features
The only real “broken” feature is the last crate pushing puzzle, and requires the player to turn their character left and right to push it in. Other than that, clipping issues with the elevator and doors are the only problems. For a 2008 game, it is preserved quite well, but this may be due to a fairly recent update in 2017.
