alternative to Warcraft 3 Castle Fight?

Oh boy, I played a ton of this back in the day.

Does that work against computer or do i have to play with somebody else?

I'd like to see an alternative to Footmen Frenzy

Besides all the DOTA clones ou there.
Do anyone know any games based on WC3 maps?
Would really like something like Vampirism / Kodo tag / Trolls vs Elfes (And alike)
But anything based on any maps?

Starcraft 2 version.

Speaking of W3 maps, The 3 Corridors and Battleships were pretty fun.
