GTA: Band of Heroes
A thief comes to the castle to steal a rare treasure, but when he got there other thieves beat him up. He goes after the thieves and that is where the story starts. The game is played via mouse and the idea here is to get to the finish line. You would need to battle countless enemy. Others would join your noble cause as you make some progress. Collect some coins to get more points. Get the power, so your weapon could be powerful. You have a special attack and it would charge overtime. The game gets harder and harder as you make some progress.
