When you nuke something, there is normally a red dot that appears. Well, guess what, I know a trick that makes this red dot not appear. It's simple. Just nuke any air unit. The red dot will not appear. Also, try nuking a Dark Archon -- you cant see the dot. Try nuking a floating building like your Ebay or your allies observer (with his permission of course). It'll all be worth your while when the enemy can't find the red dot. Also, you could even get away with nuking his overlord, wont work against computer because he'll see your ghost, but against people, there is no red dot! You could even try creative strats like sending in a dropship with matrix on it to nuke -- to hide the dot of course. What a neat trick!!!

CreepColony's Opinion: Hmm, I'll have to try that.
