Looking for old ROC mass-kill hero-control custom map

[Mansew]

There's a wide, big center portion (grass?) field where most enemy units come. They also appear in narrow lanes at the left and right edges next to the main, center portion. I think enemy units are summoned from human Barracks. I'm not sure if you truly had to destroy the production buildings, but I don't think so. The players simply have their own hero, with no other supporting ally production buildings or units.
