Greetings, test subject, and welcome back to the Aperture Science Volunteer Employee Gravity Liberation Testing Program. If you are reading this, the Luna-C Enrichment Center assumes that you have successfully navigated the first three chambers of this program. If you have not, you should immediately proceed to the beginning of the test series and start there, as attempting this test without the proper low-gravity acclimation and basic movement skills can result in various forms of personal discomfort including but not limited to: nausea, disorientation, frustration, compound fractures, laser burns, violent death, loss of promotion opportunities, and unexplained gaps on your resume.

Luna-C 01: Intro to Lunar Gravity
Luna-C 02: Featherfall
Luna-C 03: One Small Step

Due to the physical and mental exertions required to complete a typical Aperture Science testing course, the design of the following test chamber originally included a gallery of vending machines which disbursed energy drinks, candy bars, methamphetamines and other motivational materials to encourage test subjects to continue onward. Unfortunately, due to budget restrictions and low employee morale it was necessary to remove these vending machines and return them to the Luna-C residential wing. To compensate for the lack of motivational materials, they have been replaced by the popular and inexpensive Aperture Science Sentry Turret, which nine out of ten surviving test subjects found to be far more motivational than nutritional supplements.

Revision 2:
- Blocked several possible exploits.
- Restored the missing clip brush keeping the player from falling into the panel recesses.
- Remembered to pack the custom signage textures this time.
- Fixed the corrupted lighting data.
- Fixed dupe turrets spawning on reload.
Revision 3:
- Fixed an exploit.
- Minor detailing.
Revision 4:
- AIR CONTROL! For those of you who've missed being able to air strafe, I've done enough testing to be sure that I can re-enable it--with a few physics tweaks to ensure it doesn't break the map.
- Fixed the mysteriously disappearing indicator lights for the cube dropper.
- Fixed several exploits.
- Fixed a few minor texture and geometry errors.
- Visleaf optimization.

Note: as with all of my maps, I will never require cube-throwing, although there are certainly parts that can be solved using it. If you think you have to throw your cube, there is an easier approach you haven't though of yet.

When you're ready to move on, Test Chamber 05 is now complete!

Great map. Logical, tricky, unique and fun!

i did it, but probably incorrectly... i got past the second to last turret by using the corpse of a dead turret nearby as a shield... and as for the last partible barrier, i put the weighted sphere in an infinite portal loop so as it fell it disrupted the laser for a fraction of a second, then i shot a portal through during that time. this was a really cool test!

After all that I kinda expected to actually walk on the Moon

before playing portal 2 i thought the enrichment spheres were located on the moon

I can't believe these people. They complain of your series being too easy, and now that they have difficulty, they complain again.Catching the cube can be done 100% of the time by getting to the launcher asap after pressing the button (fastest possible approach). The end bit, I merely jumped up with the cube, let go, and shot a portal before it fell. Others have described having it fall down and up two portals on the floor, so that you'll have more time to shoot when it's on the apex of its rise
