Description
Flash version: 8, ActionScript 2.0.
The idea is that one can use the game as is, or use it as a template to make their own scrolling shooter type game. Instructions are included which explain how to swap out the following graphics with your graphics: main ship, enemy ships, projectiles.

Different enemy behavior for different stages:
All enemies fly in at once stages1-4
Different enemy stage 5
Staggered fly in stage 6
Different enemy stage 10
Repeat of different enemy from stage 5 on stage 13
Difficulty changes based on stage:
As the game progresses the behavior of the enemy ships is automatically updated by the action script to be more aggressive.
Infinite Levels:
If the programmer chooses the number of levels can be infinite, default stages are created automatically and do not require input from the programmer.
Random Enemy Patterns:
The patterns of the enemy are different each game (at least for the stages where the bugs fly in and land in a random pattern) so each game is unique. The attack times are also based on random numbers so they will never be exactly the same.
Background Music is an option.
Coding and Customization
Here are some of the main features which are easily changed using the actionscript:
bugSource = "beeLoopFromLeft"; //enemy graphic
bugNumber = 10; //number of enemies to start
xStartLocation = 0; //enemy start location
xSpread=200; //beginning horizontal spread of enemies
yStartLocation = 45;
ySpread = 150;
aggressiveness = 1500; //this number affects how likely enemy to attack
bugAggressivnessIncreaseIncrement = 50; //increase in bug aggressiveness per stage
newStageBugIncrement = 2; //number of extra bugs per stage
endGameLevel = 15;
maxBullets = 4;
extraShips = 2;
extraLife1Score = 200000;
extraLife2Score = 400000;
extraLife3Score = 800000;
powerUpSpeed = true;
powerUpQuickShot = true;
powerUpBazooka = true;
twoShipsAllowed = true;
backgroundMusic = false;
playerShip = "ship";
bulletSpeed = -12;
bulletSource = "projectile"

Is there a way to add credits, XML maybe. I want to develop a game website where the visitors need to buy credits to play? Multi players?
Hi Jorgerosa. Thanks for the nice comments. You can use the game and code however you want. You are welcome to use all, or part of it, for commercial games. If you make something neat though please send me a link.
