- Defender (Atari 2600) online game (atarionline.org)
ATARI DEFENDER is very similar to the Williams coin-operated DEFENDER game. However, you will find some differences in the game play as well as in the graphic images and game controls. For example, in the coin-operated DEFENDER game, two or more Alien Landers can kidnap Humanoids simultaneously, whereas in the ATARI version, Landers can abduct only one Humanoid at a time. In the coin-operated game, you can accidentally kill a Humanoid with your own missile fire while attempting a rescue, and even lose a life in Hyperspace. Such tragedies cannot happen in ATARI DEFENDER. ATARI Humanoids are invulnerable to missile fire, and Universal Space Ship Defender will always emerge from Hyperspace intact.
- Vashon Glaciation (Wikipedia)
The Vashon Glaciation, Vashon Stadial or Vashon Stade is a local term for the most recent period of very cold climate in which during its peak, glaciers covered the entire Salish Sea as well as present day Seattle, Tacoma, Olympia and other surrounding areas in the western part of present-day Washington of the United States of America. This occurred during a cold period around the world known as the last glacial period. This was the most recent cold period of the Quaternary glaciation, the time period in which the arctic ice sheets have existed. The Quaternary Glaciation is part of the Late Cenozoic Ice Age, which began 33.9 million years ago and is ongoing. It is the time period in which the Antarctic ice cap has existed.
