I bought and downloaded it this morning and played through a couple of missions.
I am going through with my first playthrough character and was level 43 when I went there. Turns out it's a nice'ish level for it as most mobs you encounter at the start area is about level 42-43. There are a ton of zombies though! Heaps more target to shoot at than the main game.
I'm going to complete the Zombie Land and then go back to the original game to complete my 2nd playthrough.
