There's a way to event it (which I believe Reives used).
Take a screenshot of the map and characters and save it in the Pictures folder. Then use the "Show Picture" and "Move Picture" commands. Increase the "zoom" ratio and after a couple of "Wait frames", zoom back and erase the picture.
This is assuming you want it in a cutscene; if what you mean is zooming in on the player at any given time (probably by pressing a key), please do say so.
