Going to a LAN in a bit, trying to remember a map we used to play!

There was a custom scenario we played back in the day and I cannot for the life of me remember what it was called.

It was set up like a castle blood map, 8 players each with their own fortified spawn area and a big battle area between everyone.

The difference was that instead of multiple castles you had a relic/wonder/castle/tower or something like that and behind your spawn area there was an island with a unit on it. You moved that unit onto a flag and it began spawning that unit in your fortified spawn area very quickly.

After X amount of kills you would be given an additional slightly stronger unit on your island and now you could move the old unit off the flag and put the new one on the flag and it would start spawning.

After a while you would have many different units to choose to spawn to help counter what ever was coming at you.

Any idea if this still exists? I spent so much time in this game mode that I'm sad I cannot remember what it was called.
