One Cube should stay at least. Maybe you put the Sphere on: that starts another fun-element, but makes you also to start over with the Cubes.
So just try again and don't give up, you must have been so close to the exit, anyway.

I can't figure it out. I've put all three different cubes on the button connected to the exit and each time all three cubes respawn. What am I doing wrong? Is there something I've missed?

Like you said: it's a fun map! And you had much with the blue gel, so I'm 100% satisfied ^_^

Again a bit hard to get what does what button (what will respawn a cube or desactivate a fizzler for exemple) but still a lot of fun with blue gel :p
Oh and I used blue gel to solve the puzzle easily X) You can place the ball on the ball button from the lower place...

I'm GLaD, I could surprise you!
The Sphere is not part of the puzzle, but a funny bonus for the end.
The blue gel is just for having fun, for those who haven't had enough of this chamber ^_^

This is a fun "kill all turrets" chamber.

The respawning cubes at the end was an interesting surprise.

I made it all the way through without using the bounce gel. You can place the sphere into its button pretty easily by lifting it from the floor below.

Yeah thanks, it is meant to be a fun map after all! But as it would have been too easy, I created at least a little puzzle element in it. :)

Fun map. I got a bit confused at the end with the cubes that kept respawning on me as I was trying to activate the exit door, but finally got a sequence that worked :-)

thumb up
cheers

thankyou.
happy christmas

Doom! Yeah, I also think of such a map ^_^
I think I have to look out for it instead of building myself ... for the "Cube" I didn't find a suitable one, so I build one. :) I hope, there is somebody out there, who survives and gets out ;)
Ok, thank you for the hint - and I wish you a happy X-Mas!

as I said, I already took out all the turrets exept the ones that droped to their deaths.
but that was because I activated a button.
their is a mod that can tell you how many turrets their are & how many you have killed.
I think it was by carl kenner, but not sure.
him or not, I came accross it in a portal / doom map he made.
the map looked like doom, but their were loads of turrets & you had your trusted portal gun.
it is in the portal workshop & more of his.
hope this helps :)

Okay, depending on how you play, you can finish with the sphere instead of one cube ... so different ways are possible. Do it as you wish and you now can take out even all of the turrets.
I wish, there was a counter, that can count deactivated and destroyed towers to make a further puzzle element out of it. Wouldn't it be a challange for BEEmod? :)

Yeah, I didn't knew on creating the map, how powerful lightbridges are, so I will do an update on the 'walkway'. You won't get stuck behind the lightbridges on the laser - here is a way out (<click) even without a turret.
The bouncy gel is for pure fun, if you do the sphere bonus, maybe to take out more turrets.
You can use every method to kill the turrets as you wish, this is intended to be a fun map anyway :)
But please tell me, how did you finish with just two cubes? (Sphere is just bonus)

just had 2nd go.
turned off fizzler & liberated the last cube.
used the light bridge near exit, this time, to get to the turrets, guarding the cubes.
did not use bouncy gel, but enjoyed killing all the turrets.
well, some jumped to thier own deaths, from hole in cieling.
but I killed the rest.
I call this a fun map :)
I enjoyed it, & it is your best I have tried so far.
I would have all cubes guarded by turrets in this map.
so the player, would have to liberate all of them.
also make them all essential.
nice to have so many portable areas.
most maps don't have so many, because of stopping exploits.

I tried using portals, to place the light bridge, along area rail platform goes.
the moving rail platform makes the light bridge lenth vary.
but also makes part of the light bridge invisible (weird bug)
you can still walk along invisible part of light bridge.
which is neat :)

got to exit:

just did my 1st run.
fun :)
will have another go, as never used:
1 cube, bouncy gel, & left some turrets alive.
thought for a moment, that I was traped the side of the light bridge, with the turrets.
but I positioned a turret (the only live 1 in this area, to make me pay attention)
I then jumped on his back leg, then his head, then into the portal.
the other side, did the same, exept, jumped off turret, over light bridge.

Yay, you have it fixed! (insider) ^-^v
Thank you - and yes, it was rather build for fun anyway and I added some more elements to make it a little longer to play, as I found it too boring otherwise.
The blue gel is just for fun, if you want to hop crazy around the map and not needed at all ^,^
Hope you also enjoyed the "bonus" at the end ^.^

Good turret map. Not too easy to kill some of the turrets like other people's maps, but not ridiculous either. The puzzle element was mildly frustrating, but bearable. Only problem was not knowing what did what until you did it. Such as finding the blue gel on accident as it wasn't obvious it was in there and there are no glass panels to see in there. Overall, a fun map..
