Well, what you're proposing isn't DIRECLTY possible, ie, have all the spawns that WOULD appear normally suddenly popping into place. I think you could manually make like 20 or so boss fights that spawn when you hit the glowie (maybe have an ambush spawn off the glowie too, just for kicks).
To do this, set the map for "Empty". Place your glowie. Then make a Boss fight (select the boss you want and what kinds of minions you want around him), set the number to whatever the spawn limit for the map is, and select to have it trigger once the glowie objective is complete (should all be under the "Settings" tab). That should do the trick.

Allied to all sides so that no matter what, I'll come out on top!
Oh, and Crimson demands you play this arc-> Twisted Knives (MA Arc #397769)
You could also set for a massive battle to spawn after your glowie, which could potentially fill the map with lots of baddies fighting you and each other.
Anybody know how to setup up a map with no enemys on map until, you click a glowie to spawn them all. Any help will be grateful. thanks
