Android game based on the Arthurian legends. Like other Gameloft games it has in-app purchases, but it's still possible to progress without them.
King Arthur has gone mad, fueled by his jealousy toward Lancelot for romancing his wife, Queen Guinevere. In his desperation, Arthur has been tricked by his sister, the all-powerful sorceress Morgana Le Fey, to open the Hellgate and allow all forms of demons to enter the world. Meanwhile, Morgana has captured Guinevere and holds her hostage on the magical island of Avalon.
Damn. I paid like 5 times as much 4 something years ago and I still haven't even gotten around to playing it. Should have waited.
