Chikyuu Kaihou Gun ZAS
It’s the 21st Century, and mounting pollution has forced Earth’s population to
flee for Mars. Since that time, Earth has been uninhabited… until one day,
super-intelligent robots from another galaxy descended on the planet and took
over. While the robots did manage to solve Earth’s pollution problem, they
have done something else that may not be just as magnanimous: they have
reshaped the Earth in their own image! Now, an ad hoc liberation army sets
forth to rid the planet of these mechanical maniacs and make the Earth safe
for humans again.
Chiky ū Kaihō Gun ZAS is a shoot-em-up game in which a single player must
shoot his/her way through 5 integrated stages of mayhem to save the Earth from
the robot invasion. (The player can choose to start playing on any one of the
first four stages, but can only access the final stage by starting from level
1 and fighting through level by level.) While the player only has a single
weapon (which can upgraded) and a shield, he/she is assisted by a pair of guns
that can be moved in a straight line from the ship, giving him/her more
firepower when combating the enemies. Plus, the player can detect approaching
enemies from the background. And the player will need every one of these
advantages, because timing is key if the Earth is to be saved!
