Bill Witts wrote this as his first non-trivial Java program back in 1996 as a challenge to write BattleZone, the once well-known Atari arcade game, in 24 hours. In the end, it took 32 hours. Bill wrote the original Atari-approved Quicksilva BattleZone game for the Sinclair ZX Spectrum back in 1983-84, and it took perhaps 15 months in total, so this is a quite favorable comparison of Java versus Z80 machine code (although it helps that your computer is probably 2-3 orders of magnitude faster than a Spectrum...).
In order to avoid adding more hours, we have left out the demo screens and the other frills. For instance, all controls are keyboard based - clicking the mouse restarts the game. Keyboard instructions are on the intro page. Remember, you're driving a tank, and the controls drive the caterpillar tracks independently. Don't stay in one place for long, kill everything that moves, and watch the radar!
By the way, source code is not included - no sizeable code written in a day is pretty, and we wouldn't want to offend anyone. Just enjoy the experience!
