Ok...trigger difficulties, summed up:

ok, stupidest question first:

How do I get it to display a text message? like, have it print:

citizen: ahh! it is godzilla! run for your lives!

or similar.

next, how do I, en-masse, give units controlled by one player to another? I found the trigger for single unit transfer, but.

last, how do i reveal a small portion of the map for player X?

1: Game - display text (or something like that)

2: Pick ever unit in region, and give picked unit to Player X.

3: Create enabeled visibility modiefier on region.
