how do i beat this!?

Not even going to try this solo...

Super fun map, me and my friend broke at 1 point. At the last part after we died 2 cubes were on 1 side and without dying pixel walking we placed cubes on buttons, then when dropped we were able to jump down to the very bottom without dying. 10/10 would recommend.

Thumbs down due to inability to complete map. There's an invisible wall at the doorway to the exit tubes where the turret was.

WTF IS THAT??? We couldn't do shit, stupidiest map EVER!!!

too dark, we need more light!!

The last part with the disco is so messy I thought the level broke, and there were way too many Glados comments upon death. The first three levels were better but this was still pretty cool.

Pretty fun, not too hard, just have to die a bunch of time to figure out the mechanics. The map doesn't function correctly though, theres no death for falling to the floor after the last laser puzzle, forcing you to use kill and noclip command to reset though developer console. We also had to, like some other people in the comments, use noclip to skip an invisible wall to complete the map.

When arriving at the disco and destroying the turret we couldnt get passed a invisble wall and we had to noclip through...

just an awesome pack, thank you man!
hate to say this but I'm agree that this is DLC-worth enjoyment

Great part 1-3 but part 4 is where it takes a turn for the worst. Too punishing.

You fucking psycho!

Tried this test chamber again with another co-op partner. It's like a loop of character deaths trying to figure out what to do...I got stuck in the respawn chamber agian...

Not sure what happened. I got stuck in the respawn chamber. It didn't drop the character out of it... Had to abort the map....

Best maps in workshop. Need more parts :)

Im with idiot. But please, try fo fix that, it'd ve been a great map without that bug

After the 4th test, I fell into a zone of emptyness and blackness together with a cube. My partner, who was initially at the colorful ending party, somehow managed to jump of a cliff and came with me. We died alone and cold, in bugzone. Lol.

SUGGESTIONS:
-On Phase 2, there is a delay with both lasers and plates. The laser has to brake first and it has a chance of killing your partner during the brake. Maybe make it brake faster as it can get annoying with the delay.
-On Phase 2-4, once your partner dies, you get a very high evade chance of maneuvering the more you stay n the center. MAYBE make the laser go faster when your partner dies.
-On Phase 3, you can actually cheat this phase by simply walking on the railing and get the cube WITHOUT a worry. That gives you an advantage to just get on and keep doing it to get cubes (there's 2 so not much to worry) which can break the map. Possibly, instead of using the railing, make a panel that opens on button press to get cubes.
-I think you should put in GLaDOS to give it that boss fight feeling. When I saw the finale I think it deserved a boss fight while retaining it's mini-game feeling.

Best Portal 2 map played ever! Orange, you got five science collabration points... Kind of hard due to network laaaaag

The best Portal 2 map :)

For everybody who is stuck here is l little kinda walktrough for the last part. The other plans are in the planing. Enjoy it! http://youtu.be/BzDeeIPbnBs

Absolutely loved the finale. It was almost like a mini-game, and I'd love to see more challenges like this. Really original and overall, just fun! I do agree on the light show however, where mine and my friends computers were more or less crippled in terms of fps. We also encountered the bridge glitch where we couldn't go into the final room to exit the level due to an invisible blockade of some sort near where the sentry was.

Regardless, awesome work and would love to see more challenge like this.

Thumbs up on all the map sets but the last one. The challenges in the fourth map themselves were creative enough, but once you've finished, the light show tends to bring all but the most powerful computers to their knees. I could tell mine started handling a slight bit off, but the friend I was playing with had nearly unbearable lag.

The worst part of the end though was that we were stuck on the bridge and could not enter the exit room thanks to an invisible wall of some sort, right where the turret had been . There was nothing in our way. I think even with the slowdown at the end, if we could have exited, it would have been thumbs up. As it was, being prevented from the finality of actually exiting and having no choice but to force-skip ruins it. Fix that, and I'd be willing to change to thumbs up.

The first three in the set were excellent tho - some great, very challenging mental puzzles there, as well as several that require timing and reflexes.

nope

do you really have to throw the cube at the end??

Loved the maps, can't wait for more. Cheers.

THIS WAS AMAZING!

Loved this map had alot of fun!!

AWESOME COLLECTION. Liked how it challenged us. A few glitches but we managed. Hope for some moreeeeeee!

Finally did it properly lol. We were stuck in a glitch, I guess, because we died right after so when respawn the doors were already closed. GOOOOOOD LEVELS XD

The finale was difficult and irritating, because the only time we had any way to think was by delaying our death and looking around. I don't think it should work that way. We experienced the same lag ExcedrinPM mentioned.

I loved this mappack, as it contains some of the most difficult puzzles I've seen. The finale could be less trial-and-error based though, because it sucked the whole enjoyment out of us.

GREAT maps, intelligent puzzles, hard to find among the riff-raff. Don't take the thumbs down from the casuals, keep on doing what you do.

@flying hen
When you get the cubes onto the buttons on the last stage (4th) you see the the panels with cube-buttons move down, and doors bellow you open

@Exce
Yeah, I know it's a problem with the high concentration of enteties. I'd see what I can do when I'm able.

Thanks for playing!

Great pack but the light show at the end made the game horribly choppy and I'm running on a beast of a computer.

Played this part 2 times both times beat all four stages but door does not open. We can't even die so we have to restart the stage again. What are we missing?

Very good map.

Absolutely brilliant!

Was a lot of fun. We needed some new tricks and i think one map we didn't solved as intended but so long the best pack we played so far. Thx

Best Co-Op map pack so far. I would have gladly paid 5-10 bucks for a DLC this AWESOME. Most other maps were boring in comparison to this. Very Hard, very cool! Thank you very much for 4 hours of entertainment.
