Help with finding a PvE hero map

[schizoi6]

Hi all, I need some help finding a hero based map where you defend against hordes of enemies in an arena, with breaks in between to buy items, etc. I suppose it's similar to Orc Gladiators except the heroes you could choose from were your usual WC3 heroes with custom abilities. A notable feature of the arena is that it had boxes around that you could break to create cover. That's about all I remember. Appreciate any clues.
