This was a great map, especially the logic needed laser the turrets. The elevator trick, however was more ninja than logic and almost ruined the map for me.

This test shows what the campanion cube is all about

Very good job, to complete it, we have to had understood all the mecanism of portal (escpecialy the first !). I love it.

2 bugs anyways :
- In the second room i was with the companion cube, and I made 2 portals -> i cannot activate the laser or going back with the cube because or the emmancipation grid. Something like a button after the first emmancipation grid can fix it.
- In the last room I was killed by the elevator, but I think it's a bug of the game itself.

Thanks again for your work. I'm going to test your other maps.

thx for the tip, solved, but almost dammaged my brain O_o :D

Room after second group of turrets hint: Think about the very, very first thing you did with your companion cube during the Portal 1 level.
The checkpoint thing can't be helped, because of the dissipator fields, but it's designed so that once the turrets are gone walking back and forth is much easier.
New chamber posted to my workshop, check it out!

Make checkpoints because everytime I loose the cube I have to walk all the way back get the cube and walk back

Mostly tedious stuff, but the progression through different challenges made it less so. The last trick was a nice touch.

I don't see any solution for the room after the second group of turrets...

Great Chamber! You'd might want to know that it is possible to break it though. If you manage to throw the companion cube on the last elevator as it's on it's way up there'll be no way to bring it down again.

Featured your map in my Let's Play

I'm stumped

Good Work on this one. I think this is my favorite so far.

Yeah, i can see the intention now! I like it very much :) Especialy the way of killing turrets and the idea of the box in the third room. Good job :)

Fixed. Try it again!

@el Fuego (I am author): I realized the thing about the turrets earlier today, and I may edit it so there are 2 rows (impossible to cover then.) The jumping on the box is intedned. I will examine the last room, thanks for your feedback!

I am not sure, what is author's intented way to pass this level, but i think, i have done it differently... Near the sentries, i used companion cube to cover my self and also to kill it. Later in the third room, I steped onto the cube to be able shot portal behind the blue line and the fourth room, i ignored comletly and simply used portals to get me an cube on the high platform a reach the exit :)

Nice idea, and very fun :)

Nicely done! It's good to see some more Companion Cube levels. Thanks, mate!

Awesome dude!
