One-man studio Cataclysmic Games has released a demo version of When Asteroids Attack, an upcoming Windows shooter inspired by Atari's arcade classic Asteroids.

While When Asteroids Attack's mechanics are simple, there's a great amount of gameplay variety here. Stages range from simple screen-clearing missions to scrolling shooter sequences, with a number of alternate gameplay modes and optional challenges found throughout the single-player campaign. Some of the bonus objectives are quite challenging!

When Asteroids Attack will be released as a digital download on November 9th, and can be preordered for $4.99. A Collector's Edition, which includes a physical copy of the game, hand-drawn art, and a personal thank-you note, is currently priced at $11.99.
