                          save the virtual reality of Beachfront from a
                          lethal virus before it can spread to the rest of
                          the network! Find the four keys to the Core,
                          fight your way to the evil Darkscythe, and stop

By default, these materials have been filtered out of the game, and it can
be played and understood without them. However, if you would like to see
intense and objectionable material when playing, you can enable them from
the opening menu, or enter "?-filter" during gameplay. You can then enter
"?+filter" to reenable it.

* Difficulty Warning *

This game may be a little tough! You may have to fight fast-firing foes in
tight spaces, and shoot out their bullets with your own. You may reduce
the game speed to get through a difficult part of the game if you have to,
but please return to normal speed when you're through!
