_Poizone_ is a Pengo variant with an ecological theme. The player controls
the penguin Zozo as he attempts to decontaminate each of the game’s 50 levels.
Like in Pengo each level contains blocks that can be pushed or destroyed. It
differs though in that the main objective is not to kill the enemies but to
destroy a number of toxic blocks. To complete a level 90% of these blocks have
to be destroyed and it has to happen before time runs out.
There are eight kinds of toxic blocks and each has its own way to be
destroyed. For example some blocks has to be destroyed from a specific
direction while some has to be pushed away. Destroying a toxic block in the
wrong way leads to a lost life. A life is also lost when making contact with a
monster. Some other blocks exist such as power pills that can be used to avoid
monsters and diamonds that give bonuses.
