The supposed 'alternative' test chamber 21, this test can be described, in this authors own words, as this; Lego.

Turrets, lasers, a secret, whats not to like? Go out there and make some science happen!

Science 21

Short, unenjoyable succession of corridors featuring a minor puzzle made even more obviuos by the lack of any alternative. Style is reasonably varied, average looking with sudden drops (like the low poly panel holders).

But the map's essence lies in its "secret" room: a portable wall like any other, which kills you when you get there.

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

Nice map, everything worked for me. Puzzle was P2-like ie linear with not much by way of alternative solutions. Thanks for creating.

yeah I must say a little bland and simple/linear but it did have me stumped for at least a minute or two and it is complete and bug free, so, 3/5

also that little trap down the grate with the turrets was pretty stupid I thought there was something there and tried to kill em (I know I had time to run up to them but you blocked it off)

Totally don't like that. It's all about secret wall moving and show you where to go, except the secret with godlike turrets that kills you.

The puzzle is rather obvious, and the rooms are rather blah. On the good side, there were little surprises. On the bad side, one of them is deadly. I'll count my blessings that this wasn't another first map monstrosity, and give it 3/5.
