I can't find my favourite map

Hello!

I'm already searching this map, for like 2-3 days, but I haven't found it yet. Could you please help me?

Its a two-player map, players do not play against each other, they try to clear a big labyrinth of monsters together, and I think, kill Archimonde in the end. Both player have 5 heroes (Paladin, Priest, a ranger, I can't remember them), you can choose one of them at start. You get souls for each monster kills, and if you collected 200 or 250 of them, you can choose one more hero, so at the end of the game, both player can control all of the heroes. For creep kills you get gold (of course), you can buy wood with gold, and with those, you can buy soldiers (from Militia to Ogre Magi if I can remember...) and buy upgrades to those soldiers and the upgrades affect the heroes too.

The players' bases are in the middle of the bottom of the map (omg XD), the road to them looks like an up-side-down Y.

If you know this map, please give me a link.

Thanks.
