.. Getting to the password holder

When trying to access the third floor, it's clear that someone is hiding in there.

They probably know the password.

The room's super secure - no keycard reader, no back entrance.

We'll need to approach from another direction.

The only thing above this room is the roof - there may be a way down into the room from there.

The vent would be a great way in, if it weren't so rusty.

If only we had some superlemonkola!

That's not a bad idea, actually - unions probably mandate that this tower has a break room!

There are only so many possibilites; make sure you've searched the tower thoroughly.

More specifically, make sure you've explored the floor with a broken door thoroughly.

There's more to see than just a broken door - by moving to the far right, you can go to the back of the tower.

Shame about this hydraulic cart blocking us.

Have you tried moving it out of the way?

('Grab' the cart to move it.)

As expected - a room with a vending machine!

If that wasn't good enough, there's a superlemonkola machine ready to eat our coins in the corner.

All of the money, none of the drink?! That's outrageous!

(Doesn't it make you want to hit things?)

Hit the machine to get your drink, then use the cola to remove the rust on the air vent cover.

You'll then be able to loosen the screws with your wrench.

I'm getting really tired of these nerds, man! He's so scared that he's blocking the vent cover with his body.

We need something that can force him out of the way.

Something with explosive potential. (Like an explosive.)

There's probably some good stuff to find in the rubble - return to the ground and see what you can find.

Grab a grenade from the ground near the keycard-locked door, then use it on the air vent to give the nerd an explosive surprise.
