I love tower defence games and I played quite a few. This is my first time playing a Kingdom Rush game and I’m shocked by how tough Frontiers is. Changing the difficulty from normal to casual doesn’t help much either. It’s not the kind of fun challenge too. It started nicely but quickly ramped things up. I’m bowing out of this for my sanity. It’s a very typical tower defence game. So it’s not like much is missed by not playing Frontiers unless you’re a hardcore fan looking for challenge.
