This is a simplified version of the arcade classic.

Screen shot of Invaders running.

Use the "<" key and ">" key to move your ship, and the spacebar to fire. Use the spacebar to restart the game if your ship is hit.

Download Invaders (Requires Microsoft .NET Framework 2.0)

There are also some alternate graphics and sound files which you can use here (just for fun!) To use these you need to download and extract the invaders game to a folder first and then extract the files in this zip over the existing *.jpg and *.wav files.

The C# project for this program is here (Program.cs is the main file)
