Interesting concept.

Good logic puzzle. The idea of no portals put me off a bit, but I was wrong. I couldn't get the secret chamber to open, even after reaing the hint, so 'noclip' to take a look - nice one.

Thanks. Yes 100% pure logic :P

The Zero Portal Principle: all puzzles are directly proportional to their complexity.
Nice work on this one :p2cube:

I enjoyed this one a lot. I couldn't find the secret till I read your clue. Cool little hidden chamber. Thanks.

The 3rd screenshot was made it the secret, I posted a spoiler text below in the comments with a hint otherwise you'll almost won't find it... :P

Wait, is the third screenshot from an earlier version of the map?
I don't see any turrets in the current version.

It looks so complicated at first. However, when I Looked arround and saw what is where, I had an idea of what I had to do and from then on everything seemed so logical and, in a way, straight forward. Although I'm not a big fan of laser puzzles, this is one of the best laser puzzles ever, even if it doesn't contain portals, but that's actually where its charm comes from.

Nicely done! *clicking the 'favorite' button*

This is one of the highest quality tests I've found. Well done.

Good puzzle without portals :) I tried many combinations to find the hidden secret. Maybe it would be better not to let anyone know that you put one there or not have a secret at all... Now I know what not to do to my subscribers. Thank you :)

Just went back and played to find secret and found it on second combination that I tried (Don't think I would have tried many more if that didn't work. lol). http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=492164567

Nice one!

Used the hint (sigh) - there are just so many permutations otherwise; and LOTs of luck: great payoff though!

These kind of tests impress you to think logically and consider ALL the possible actions - nice!

The main puzzle's great!

About the secret - well, I used cheats (mat_wireframe) just so I would know what I was supposed to be looking at (and also host_timescale because I got tired of walking everywhere xD)... but... no luck here either unfortunately.

And I thought jgaultney and I were good at finding secrets ;)

Hehe, small hint : single fizzler button ; exit collector.... near exit, panels to the right open :D
I know it's very hard to find but that was my intention. You can find it by trial and error and some luck I guess....

A fun logic puzzle that was made slightly easier with no portals :) No luck on that secret
however. I could not find the slightest hint of where it was located or what might reveal it.
I did try several combinations of buttons and laser collectors but none that I tried worked :)
