Or, we could just use neutral lings/slightly different tile that's unbuildable.

NOEZ! Takes up too many units!

So I just build three machine shops and then do the trick? How do I do the "jump" trick?

With a probe, get right up against the building you are trying to hop, then build a pylon behind you, pushing you onto the building.

With an SCV, build next to the building, and cancel right when your SCV is floating above the building.

With a drone, get the hack called Oblivion and press 0 on the number pad when your drone is below the building, your drone will float slowly up.

For all, you can also unburrow units below them to get them to go over the building.

I still don't get how I make my probe, hold and spin, the head of the Terran Missile Turret. Does it still atack? Can I move the probe while its holding it? Im to lazy to test/crash the game another 20 times.

You can move only.. right I think it is. (Right or left). Attacking I doubt, seeing as how if you stop you crash.

Ok, I shall try to atempt this glitch, and I will keep track of how many times I crash before it actualy hapens. Wish meh luk.

You could have just asked for my help, I've been doing this glitch for ages, and I know it like the back of my hand.
But hey, if you wanna foray it yourself. go nuts
