very cool

Absolutely fantastic chamber, as was the previous in series I played. Thought it was a spaceship from moment it started. Gravity changes makes it more immersive.

Awesome series:-D

Somehow you managed to make turrets even more fun to knock over, and the soundtrack goes really hard. Excellent work

whre part 5?

Nice! Not a fan of the overlapping laser and cube button; if you want one cube to do two things at once, it might be better to just get rid of the laser and assign the button to both outputs.

Excellent level.

Battle against turrets really well done. But the last part involving passing the last fizzler is gimmicky...

Best battle with turrets ever

sorry, the most of your Chambers:NO Way

I think I did it wrong, I just threw a turret into the laser to block it, brutal, but works^^

Cool Map with some sidechambers

Very very freaking cool. Thank you!

That last mini puzzle was pure genius. Thank you :)

You have to get the hang of jumping. it took a while but I got it. Good game.

in the second room (with turrets) it is impossible to jump to the button without the help of a turret

wonderful

Pretty easy but a enjoyable map overall.

Portal A on floor below laser. Portal B on ceiling above. Drop cube through A, switch B to floor beside it. Cube comes up from B and hovers for about half a second in front of the laser beam, blocking it and allowing plenty of time to open a portal in the exit room.

No split-second timing, cube-throwing, or portal-spamming required. I just didn't teach the solution well.

Very nice, but in the last puzzle, what i have to do? Throw the box and shot very fast?

Last puzzle was incredibly rewarding once I figured it out. Awesome chamber.

Not to fun, timings are a bit short for the cube and for the last part at the door.

I can't catch the cube..

Great puzzle! Thank you!

Very cool! One of the best!

cool!

tedious not fun at all.

Another nice entry in the series.

Nice, preaty hard :)

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

I have a problem, a box got stuck under a ramp, and I can not reach for removal!! i have a screenshot but i can't publish image

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

One of the best map in the game !

I love maps with turrets that allow me to do a pacifist run (100% turrets still active by the time I got thru the exit).

I can assure this is the best comunity map I played so far
Congratulations!

Floaty! I resorted to dwarf (er, cube) tossing at the end... No turrets were spared emacipation in the completion of this test.

can you make more?

Holy cow! what a great puzzle. That end took persistance. digging these!

Could you please add more autosaves. This one is kind of long.

Real good map. The end was a little too trickey. I got it by creating a speedfall ceiling floor portal pair and just kept zapping portals until I got the timing right.

Excellent! Original and fun. Keep it up... :)

I liked this chamber. Slow-falling cube was fun.

Last bit was difficult but I enjoyed the rest of these maps.

@Quaternary you can also create a lot more time by putting both portals on the ground next to each other (both under the red laser), and then jumping in the air next to one of them, holding the cube over the portal, and then letting it go at the highest point.
It will block the laser for for a moment, and then for a moment again when it comes up through the other portal .

Love, love, LOVED this puzzle! Great job!

absolutely fantastic, particularly the bit right at the end. wonderfully inventive

For everyone having trouble with the timing in the last room, you can gain a lot more time to place the last portal by putting a portal on the floor and ceiling, leaning down into the bottom one (not dropping it from standing height), and dropping the cube from the resulting short height.

Awesome puzzle. Very funny. Thanks.

Turrets highly explosive. Handle with care
