criticalmass [options]


This manual page documents the game Critical Mass. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

criticalmass is a space shootemup similar to Galaxian. The basic idea is simple: you move your ship back and forth at the bottom of the screen, shooting up, while bad guys fly around and shoot down.

Additional documentation is available in /usr/share/doc/criticalmass/Readme.html .
