Title says it all.

Extended unit deaths.
Basically you create conditions with ridiculously high death values depending on unit IDs. Like this:
Player 234584 has suffered 234584 deaths of unitID:23543 (random example with wrong values)

With this method you can read directly from sc memory making it possible to check for things you normally couldn't. Examples are screen pos, unit hp and many more.
Before 1.14 it was even possible write to sc memory using set death actions. But they were patched by Blizzard because you could even write outside sc memory and so it was theoretically possible to program viruses into maps.

If you want to know how to actually use EUD's and how to find the correct death values and adresses read the numerous threads about EUDs in this forum.

Note that when using EUDs, you run the risk that they will not work after a new patch, it does not always happen, but there is a chance of it, so if you make a map that completely relies on them, you'll either have to just let it die if a patch kills them, or edit all your EUDs.

And search for some maps in the dldb, keyword "EUD".

Also, your grammar is terrible.
