Here lies the remains of a 1942 clone I started writing. Grab it, play it.. laugh at its futile nature. The source is available over at forty-hour-dev.dev.java.net

You can download it here. The zip contains an executable Jar. In windows you should be able to double click on the jar. Everywhere else you'll probably have to do something like:

java -jar sots.jar

You'll also need the latest Java Runtime Environment (JRE) to run it.
