Wow! Fun map but above all outstanding visuals! Thank you Sprowl for the great time I had playing it!

The other comments are right, the green was awesome - adding it to one of my collections and Following. Thanks for the beautiful fun:)

Got through it OK. Awesome level.

sehr gute map

Not very challenging, but what a map ! Lighning, ambiancy...Thumbs up !

And the panel cutters, Shredders, Tubes, Convater belts, Best backstage map ive played in ages!

That intro was awesome!

It was purchased ?

What happened to the page?

The map crashes

Beautiful map! Thanks!

I managed to get trapped in the beginning (before any of that cool NV stuff). Better set the trigger_hurt a little higher.

My only other complaint is the beginning puzzle itself. I was stumbling around and didn't even notice the breaker by the disassembler, let alone what it controlled. Other than that, this is a stellar map! Really showcases what goes on behind the scenes at Aperture Laboratories!

Wow. The design of this level was proffesional and I couldn't stop gawking at every detail. There wasnt much puzzle, but thats simply because its only the intro. It was sometimes a bit too dark in the nightvision portion, but otherwise I loved it!

when the nightvision went on, i half expected to encounter xenomorphs

Wowcool! I'm just afraid that I may have missed a secret spot. Thanks!

Very cool! Excited to play the rest!

and in co_op mode there is some secret chambers where GLaDOS thurns on night vision on.

i get stuck when night vision comes onthe gate shuts and i cant do anything.help please

Glad you guys liked it. I hope nobody got stuck for to long, because there aren't any real puzzles in the map :P .

i got stuck at a point:/

The assembly cinematic as well as the night vision activation were spectacular. But,one question; How does one create the effect of night vision,like this?

I liked the nightvision! I'm going to play the other maps.

cool map

Hey nice map, I liked and will play your other maps.... Thumbs up...
@lol ( <come on bro. I know you don't any help.> :) >> ) If you still need help I'll tell you next time we play.

This is really good, but can somebody post a link to a solution?

You had me at the cinematic assembly, time to play the whole collection!

Fantastic and a bit creepy. Loved it. Thanks for your work.

Great atmosphere, looks amazing, looking forwart to next map.Thank you.

I don't understand why you suddenly went into night vision, but that doesn't make the map any worse. 6/5.

wow that was awesome good job implementing the night vision

Me too. I'm stuck after jumping off the conveyor belt. There's one portal surface round the corner - but I can't see any others. Dead end?

I couldn't get of out the first part. Plz tell me how to get out of the factory.

Holy Moly ... amazing architecure!!! Thanks for that look into the bowels of Aperture Science!

Absolutely fantastic introduction level made even better with inclusion of night-vision effect.

Awesome Map! I like that you see how you're built! Also a few good details! And the Nightvision was epic!

WOW!! Extremely nice. I love Portal because it reminds me of the days I played around as a kid inside derelict auto factories near my home in Detroit. But the detailed ambiance and sense of exploring you provide really is an extra special treat. THANK YOU!!

Its epic! I love the way i am Atlas! Great Job! You deserver cake!

i have no idea how to get past the first part XD

1000000000000000000000000000000000000000000000000000/10

Very nice - lots of details!

It's just a simple map, so I don't think it has something to do with it. Try to verify your Game Files (Steam -> Rightclick on Portal 2 -> Properties -> Local Files). After that you may have to install my particles again (it's nothing that would cause a crash). Hope that helps :-)

Crashed Steam on startup of 01 first time. Second time was OK.
Choosing 'go to next...' crashed Steam, choose go to Queue and then choose next map was OK.

This map is really cool. I loved the night vision. I look forward to playing the other cleanup vertigo maps. I don't know how in the world you made this, but its awesome. Great Job

Wow that was the best map I have ever played, great job!
Love the cutscences a!nd the night-vision
