Blockout is best described as a 3-dimensional successor to Tetris with shapes of up to 5 cubes arranged in various polyforms falling into a 3D pit. Blockout remains popular as there is still an active community as well as several leaderboards. The game was ported from the original DOS to Apple IIGS, Macintosh, Commodore 64, Amiga, Atari ST, Atari Lynx, Genesis and arcade, with the Lynx version faithfully ported by the original designers, Aleksander Ustaszewski and Mirosław Zabłocki. The original manual is available courtesy of archive.org (albeit with several inaccuracies compared to the released game) and Hardcore Gaming has a good history of the game's development and subsequent ports.
This run by dwangoAC completes all levels of Blockout as fast as possible on Out-Of-Control with Fast Rotation.
