Anyone been able to conquer this yet? I'm wondering how many yards you actually go before you're at the end. I know if you get killed, you can scroll down the screen and get a preview of what was yet to come. This has to be one of the hardest feats in the game without a doubt. One berserker versus hundreds of soldiers. My best so far is 123 yards but I'm still trying. Note that I live in the US and have only owned the game for 2 days.
I think the end was at something with close to 400 meters. Then you get additional points for the mana you got left.
Just play around with the selection of spells a bit. I personally did not go for the ying-yang and sacrifice, but maybe it's possible too, to just storm everything with a ton of beserkers. I found it easier to control one (or a few when they were multiplied). It's good fun :)
I actually went for trap, poison, terracotta warriors, arrows, hammer of (mister :P) Thor. The terracotta warriors are excellent bait for enemies so you can bunch them up and combined with the arrows they can do a lot of damage. Yin Yang, on the other hand, makes you quickly waste a lot of mana and against rocketeers and catapults, your whole army will get blasted to smithereens.
