search in the workshop for the drop pod it has a little parachute attached on top of it maybe you can lern from it how they work and yes there are atuators included

I cant make a parachute. . . Is it just a bunch of wings and actuators scrambled together?

R.I.P your brain the brain didnt see it comming

(base the door off of the scp game also base the test rooms / containment rooms of that.. build a launchable "alpha warhead" that detaches with detonators (use numkey 5 for detaching) and alt W (or however you want to do it) to launch it. add a metal door on the hill for the warhead wich haas grass covering it and add a medbay and a control room AND like a little escape pod sort of thing with you can launch (put the driver seat in the escape pod) and when you reach a safe altitude the player could extend a parachute...... wait.... i typed too much.... im very sorry for your brain XD you could also add more things you wish to add to it.... good luck XD

a canteen some corridors maybe a brig have emergency doors between the corridors have like a nuclear reactor testing rooms have not too many lights because they lag like sh*t emergency lights (coloured red) some test rooms should contain things that can blow up / kill players / cause a breach (maybe) have a little panic room or lets call it a bunker wich has a strong metal door

Well, my Steam gameplay time isnt that much. And I am also not that creative, all I need to know is WHAT to add into the lab.

good luck!

after that make that legendary laboratory notice... you will be the first one to do this its rare to find labs in the brick rigs workshop and even a huge underground awesome lab... its a chance that youll end up in the front page or atleast close. good luck! also make sure to texture it more than this crappy lab i dont mean to offend your work but its true

Oh, ok. I can try that. But I can currently working on "The Goodbye Cannon V2" a cannon that shoots like 50 shells at the target.

build a self made hill

Not sure how I am supposed to make something underground.

i got a big big idea! build a big underground laboratory wich is hidden per hill mind to NOT pass 4000 bricks (if need you can exceed my limit but not too high) if you make this happen youll make my day
