TO WHOEVER THIS REACHES
Your forebearers called them many different things. Utsi. Pla Mawr. Wan Gui Hong. In your time, these names have blissfully slipped from memory. Not for much longer.

In preparation for their return, we have provided to you a compact training program for the popular "PICO-EIGHT" computer, to hone your skills in combat. Use your "Arrow Keys" to move your weapon, and "Z" to strike. Eliminate all 128, and do not let any of them reach the other side of the viewport. Turn back the simulation with "Enter" until you may achieve this with consistency. Then, press "X" however many times you wish for a greater challenge.

Below is this program's source code. Spread it to your friends and loved ones. You must all be prepared for when PESTILENCE returns.
