Tomb Robber

I downloaded the map again, but this time, the mummy that I need to kill got stuck in the gate when the cart approached. The mummy just stands there, and I can't get to it (I can't attack it), so I'll have to replay half the game (I was playing with only one save).

My Mage turned out to be too combat-oriented. No spells, but a powerful engineer. I easily defeated the mages and the Necromancer with just Titans, a ballista, and a tent.
