Datastorm
Datastorm is a scrolling shooter video game for the Amiga home computer. It is similar to the arcade game, Defender. Written by Søren Grønbech, it was inspired by Dropzone for the Commodore 64. As such, the exact gameplay deviates from Defender in that the task on each level is to carry the 8 pods through a portal, with points on completing a level for each one saved. The amount of points increases for each level: on levels 5, 9, 13 and so on, the player gets a new set of eight and the scoring resets.
The number of sprites moving smoothly around the screen is noteworthy. Some, including the Datastorm itself, cover almost the entire length of the screen.
