Here's an example of something I did with a few EUD's.
Megamedic is under attack by some rines, so she turns on her shields and casts a 1000 damage psi storm on them. Then she runs through their base blasting everything with her hyperspeed mega-yamato-gun. She sees a bunch of bc's coming in the distance with her 100 sight range (or something), so she decides to use her powers and walk across water to the next island, where she nukes the zerg hive which retaliates by throwing zerglings (Yes, through the air) at MegaMedic, killing her.
Seriously, that was a map I made back in the days of EUD. Good times.. good times..
And for you EUD Nay-Sayers, keep your anti-eud comments to yourself. People made great maps before, and they could make just as great maps now. It's not a revolution in sc, just a new fun feature to keep people interested. It isn't like WC3's sucky editor, because it isn't right there for you and you have to go to farther lengths to use them. That means, newbs won't use them and it won't become common knowledge. Why do you think most maps don't have as incredible terrain as some on SEN?
And just to clarify, EUD were a set of conditions and actions activated by using the Set Death Count action, and by giving strange numbers and unit names, like
"Set 32421234 deaths of -12491024 for player 5"
it wound up changing the memory of Starcraft, and it was the coolest thing ever in some of our opinions. It was like modding that you could play online! If blizz hadn't patched it with the lame excuse of "So it didn't crash mac users", then EUD's could've done great things...
On a side note, yes, it did crash mac users, but if I wanted to crash people, why would I bother making EUD's when I could just put an invalid unit instead?
On another side note, Damnit you lazy SEN'ers, get off your asses and unscramble it! I can't help cause I... uh... have a dentist appointment?
