Invaders is the final project of Stellman & Greene's Head First C#.

The book gives some guidance in the form of program architecture and class diagrams, the rest is left up to the reader to implement.

The game still needs some tweaking to get the difficulty right and also a rewrite of the invaders' returnFire() method.

Press S to start.

Move left or right with the arrow keys.

Fire at the invaders to score using the space bar.
