The Great Defender

You are the great defender guardian of the earthlings, a one-man army dangerous to the nail. In this 2D space shooter, you must save the humans from being abducted and made into mutated creatures who know no bounds. Fight wave after wave of enemies using strategic shooting and mega blasts. You have three tries good luck!

In this project, I was creating a clone from the original arcade defender game. However with a twist enhancing the mechanics and changing them to be more than what it was from the original game. I used OOP. Using inheritance from a base class passed into derived classes. So my code was cleaner and well maintained. I used unity3D to make my game and Visual studio to develop my core game mechanics

The difference I made with the defender remake was the Player Character could do 3 different types of shooting a single, double and mega blast and there is a new NPC which slows the player ship down.

Here are some of the scripts I made in this project

I had a lot of fun making this project on my own. I really wanted to aim to get the defender feel that most retro gamers know it by, however, changing some mechanics to allow for different styles of gameplay and a movement which could become learned and strategic. Allowing the movement to have a drag effect I felt added a learning curve towards players which eventually players would control their inputs and react fast to enemies in the game.

However, like most things, it was not perfect and if I had the time I would have liked to change I would have liked to improve on the art style a little more to make me game different from the original. Adding a boss fight generator which allowed different mother ships to be spawned at a relevant round, also allowing for player ship customization so players could have more lives or a companion to follow the player ship and shoot enemies out of space.
