## Description

_Bad Sector: High-Density Disk Edition_ is an expanded version of the
original Bad Sector which adds collectable power-ups, an endless survival
mode, and makes some changes to the behaviour of the purple viruses. The
purple viruses do not stay still and spawn red viruses like in the original
game, instead they move around just like the other viruses however in a
randomised way which makes them harder to predict.

The power-ups that are added to the game are a extra life, and pause, which
freezes all of the viruses for a short period of time. These power-ups can be
collected either by running into them or by catching them in a sectioned off
area.

The survival mode is an endless mode where you are given two lives and are
tasked with scoring as many points as possible. These points can be obtained
by sectioning off areas and by destroying viruses. However unlike in the
normal mode, sectioned off areas disappear immediately and viruses you destroy
will re-spawn. At the beginning there are only red viruses to deal with,
however as you destroy more and more of them the purple and the yellow viruses
start spawning in their place.
