Pick a play with the up and down arrows, snap with Space, and throw with A, S or D before you cross the line of scrimmage. If a zombie is touching the receiver when the ball arrives, the pass falls incomplete. Once you have the ball, run it to the far end zone. A touchdown is worth 7 points, and running into a ghost is worth 2, though it leaves a tombstone in its place. The 60-second clock only runs while a play is live, and you get four downs to make ten yards. When the game ends, put your name on the high score board. Press H before a snap to see it.
