for 2 players
X-Y-Zap is a two player game in which the players
are in co-operation rather than competition. Two joysticks are
required in ports 1 and 2. Each player controls a tracker, one along
the X-axis adjacent to the grid and the other along the Y-axis.
The object of the game is for each player to line
their tracker up with the spark which is moving inside the grid. When
both players press their fire buttons together a neutralizer will
appear at the intersection of each tracker's axis. If the spark is hit
the score is increased and a new spark appears at the centre of the
grid. A player cannot move his tracker whilst his fire button is
pressed and should the spark hit a tracker a life will be lost.
