basic basic unity 3d game needed

I need your help with UNITY-3D. I just downloaded the free UNITY and I want you to do a fighting game that can be played and set on the free version of UNITY. I want the fighting game to be basic because this is the first time I use Unity. Also, I want you to write a good report of the game explaining how you do the game and what are the tools. I want you to design six players and six stages to fight in. Each player has different skills or moves. Also, each stage needs to be designed differently. For example, one stage is an Egyptian design, the other stage is a cowboys design, etc.. sample below [login to view URL] my budget under 50
