## Description
_Vyper_ is a single screen shoot ’em up similar to Galaga where the player
has to save the universe by shooting down large quantities of aliens known as
the Yarks. The game can be played by one or two players (in hot seat) and
there are 100 different levels and 25 different kinds of aliens. The player
controls his space ship down the bottom of the screen and shoot at the aliens
above him. Like in Galaga the aliens enters the screen in specific formations
before taking their stationary places. After that they then leave the
formation, a few at a time, and try to crash into the player. Each alien type
has its own movement pattern. The player starts with three ships and after
they have been all destroyed it’s game over. An extra ship is awarded after
every third completed level.
