If your question is "Do I do something other than try to not die while the AI proactively tries to kill me", then the answer is no. In that respect, it is like the final part of the Fallen Spire campaign.
However, the "How will the AI try to kill me" is different, and the AI's goal is a bit different, and it is MUCH harder (currently some balance issues). I suggest you try it, just so you've had the experience, at least. I enjoy it, personally. There are... other opinions, as well.
Go ahead, give it a try. Won't take much more than an hour - and possibly much less >D
