Attack of the Petscii Robots

Sometime in the future, robots attempt to take over human settlements on various
planets. Your goal is to infiltrate these settlements and destroy all of the robots.
To do this, you’ll need to locate weapons and other tools. There is a transporter room
in every settlement. However, to prevent unauthorized robots from leaving the settlements,
the transporter systems have been remotely programmed not to activate until
all robots have been destroyed. Once you have destroyed all robots, you will see the
transporter pad activate, then you can step onto it to complete the level.
At first glance, Attack of the PETSCII Robots might look like an action shooter game.
However, it’s really not. Think of it more of a strategy and exploration game. While you
are given weapons to fight with, you will never win if you try to fight the robots head
on in battle. The way to victory is by examining each robot situation as a strategy.
In most cases there will be a way to defeat every robot without engaging with them
in a head on battle. The trick is learning to find all of the right tools, and learning how
to use them.
