Quick way to model low poly cliffs seen in Game of Thrones intro ?

What I am talking about is here (50 sec mark): https://youtu.be/s7L2PVdrb_8?t=50s

Is there a quick way of modeling (generating?) that kind of wall with existing tools / scrips for Blender ?

P.S. I am aware that anything can be coded in Python, but that’s not an option for me.

Bumping this up…
