Somewhere in the depths of space you will discover a long-lost missive. It is rumored to include records of an ancient and terrible event: the invasion of a once living world.
Your attmpts to open the envelope are doomed to failure unless you can locate and invoke a mystical, perhaps mythical, incantation known as
Invaders_Of_Mars.celx
Once invoked, it supposedly will allow you to select and view the contents of the communication.
Or so it is said.
