Overview (Executive Summary)

    The core game play of this game revolves around two separate, but dependent, gaming experiences. The game is designed to be played by two players, each taking control of a different aspect of the game; however; players who wish to challenge themselves can attempt to control both at the same time. We refer to these two aspects of game play as the “shooter” game and the “engine room” game.

    The shooter game plays like what one would expect out of a standard top down shooter. The player controls a ship as it travels over a predefined track, all-the-while shooting down enemy ships and dodging enemy attacks. The engine room game is more of a puzzle game. The player moves themselves between 4 lanes, gathering different colored nodes. After collecting 12 of these nodes, the player achieves something based off of several predefined recipes. These games are not completely separate. Actions that take place in the shooter game will add different kinds of nodes to the engine room game, and the completed recipes of the engine room will strengthen the player in the shooter game. The two players need to work together to keep their ship in one piece as wave after wave of enemy ships attack them.

    There isn't too much story in this game, so that they player can more quickly get into the action. There is very little text, and any story element will be expressed through the game play itself. Short cutscenes may rarely be used, if it is deemed necessary to take control away from the player. An example a situation where this may be used is just before a boss fight while we introduce this new character to the player.

    This game employs a very simplistic color scheme behind its art design. There are four major colors in the game: red, yellow, green, and blue; and these colors, along with black and white, make up the majority of what will show up on the screen. Things in the background will be more dully colored while the foreground will be more vibrant. This allows for a beautiful world that still holds functionality (players will more easily be able to tell what they can interact with).

    The game is being programmed in Action Script 3, so that it can be run on any machine that has a flash player. This includes Windows, Macintosh, Linux, as well as many other devices (though the controls may have to be altered to fit these), which allows for us to target a larger audience. The eventual plan is to port this game into an Adobe AIR desktop application as well as a Flash release, but until that point, all testing will be done in Flash.

• Gameplay and balance. What can the player(s) do? See? Hear? How does he or she interact with the game world? How are weapons or other tools acquired, used, lost? What are the puzzles that have to be solved? Does left click mean something different than right click? What kind of physics model, if any, is being used? Describe how the game is designed so that whatever options the user chooses, the game is still interesting and playable.

Technical Specs

• COMPLETE LATER
  
• Programming languages, including compiler and emulator.
• Libraries that will be used.
• Any code or engines to be used. If you plan to use a game engine, describe it and explain what its interface (to the rest of the system) is.
• Target hardware and Operating System.
• Data Structures, or better, interfaces of ADTs and classes. A list of all (C++/Java) classes and their interfaces is appropriate in this section.
• Exact algorithms. If an NPC "knows" how to walk back and forth between to positions, avoiding a large rock in between, discuss the AI algorithm (or script) that will be used.
• Back-up and version control plans. You don't want to lose 40 hours of work in tenth week!
