It's God of War for mobile, more or less: an action adventure with brutish combat, mythological creatures, and big boss battles.

You won't be playing it for the story, but for exposition's sake, I'll drop this summation here: "Become titan Prometheus as he embarks on an epic quest to retrieve the all-powerful Godfire Spark and save mankind."
We gave it a Bronze Award in our iOS review, saying that it's a "big silly blockbuster of a game that wants desperately to be on something other than a touchscreen device."
We also added that "it has a meaty bounce to it, but its lack of subtlety will likely be too much for some to take."
You can download Godfire: Rise of Prometheus on Google Play for free. And yes, it does have IAPs, before you ask.
