Emulated in MAME ! [Console] Intellivision Game
Space Spartans © 1981 Mattel Electronics.
In 480 B.C. a small Spartan force held off Xerxes and the entire Persian army, in the famous Battle of Thermopylae. The Spartans chose to die defending the pass into Greece, to give their allies time to prepare for attack. SPACE SPARTANS reenacts this battle in space, in a heroic adventure that pits you against overwhelming alien odds. You are the elite force. Stop the first alien onslaught and a new alien force appears. Hold the aliens back as long as you can and give your home galaxy time to prepare for attack!
Score as many points as possible by shooting down alien ships, before your ship is destroyed or you run out of energy. Repair damaged ship systems and re-energize at your 3 starbases. Destroy all aliens on the Sector Grid and a new round starts with more aliens. YOU HAVE ONE SHIP AGAINST A CONTINUOUS ONSLAUGHT OF ALIEN ATTACKERS.
Space Spartans, the first Intellivoice game, was begun in mid-1981 by Brian Dougherty, who only worked on it a short time before leaving to join the startup company Imagic. Mike Minkoff took over the project and developed it further. When Mike was promoted to manager, he passed it off to the team of Bill Fisher and Steve Roney, who really defined the game and made it more than just Space Battle with voice.
At the time the game was in development, all Intellivision cartridges were 4K in size. To accommodate the voice data, Space Spartans was the first to be given a seemingly generous 8K. This turned out to be woefully inadequate; dialogue had to be cut to a minimum, and the sampling rate was dropped to the point where it's difficult to distinguish the male voices from each other. Luckily, dropping these to a very mechanical sound added to the sci-fi feel of the game. Only the female computer voice was kept at a higher rate, since it adds a strong note of personality. All the voice games that followed were allocated 12 or 16K; even the foreign versions of Space Spartans (Gli Spartani Dello Spazio, Les Spartiates De L'Espace and Spartaner Aus Dem All) were given 12K each.
Most of the sound effects were written by Bill Fisher, but Bill Goodrich contributed the explosions; this was fortunate, since it helped find a bug in Intellivision II. While playing Space Spartans on an Intellivision II, Bill Goodrich was distressed to discover his explosions sounded 'thin'. Comparing other released cartridges, he discovered similar loss of sound quality in the bubbles in Shark! Shark! It was too late to fix the bug in Intellivision II, so subsequent games were tested and reprogrammed to get around any sound problems.
