Game Concept Idea

Originally I was going to make a game about robot dinosaurs vs dragons, but when I started to think about how I would go about making the blueprints for that I changed my main design.  This is my chosen game idea:

Robot Rescue

Basic Overview: 3D third person combat style fighting game, where you play as a robot trying to save it's creator after he was kidnapped by a terrorist group who want him to mass produce these fighting robots. 
Settings: The environment will be a jungle level with the enemy base an abandoned castle/research facility.
Theme: Fast-Paced combat fighting and skill building points.
Target Audience: Aimed at people who like fighting games, so from teens upwards.
Platform: the platform will be PC and Console based.
How To Play: 3D control space and using different keys/buttons to use your skills to react to your opponents attack. 
Difficulty: The game is reflex based, using your Eye-to-Hand co-ordination skills to combat against any trials you face during the level. The player will also be given a battery that will act as health, further through the game the charger will be much tougher to find.
Meaning: The difficulty of the AI's and obstacles will represent the challenges and trials you overcome when saving someone close to you. 
Selling Point: The Potential to give people the feeling that they are helping someone by rescuing that person.
Mechanics: Health Bar (Enemy Ai's also), Reload Bar, Re spawning, 3D Control Movement Inputs, Jumping, Weapon Switching, Ammo Pickup, Sprinting, and Increased level difficulty.

The 'Flow' of the game is similar to the design, the aim is to rescue your creator and survive from enemy's and health depletion.  Awards will be made clear, and finding items will be made simple with your radar (which can be upgraded throughout the game), more challenges will be unlocked as the game progresses, and the main focus of the game will be becoming strong enough to save your creator.
