Good graphics: check. Mythical creatures: check. Blood, violence, and a shamed gladiator set on revenge: check, check, and check. If all those are all on your list of "things for a good mobile game," then Gamelion Studios' Rage of the Gladiator should fit the bill pretty well.
* Stunning 3D graphics!
* Full voice acting. Each boss has its own personality, and taunts you mercilessly!
* Extremely realistic animations. When you attack bosses, the impacts and hits feel "real."
