After you select the skill level, the game begins with a playing field ofblue squares surrounded by saguaro cactuses and tumbleweeds. Aschooner is in the center of the square, and all of the saguaros are inpairs. The pairs of saguaros are generators of the alien creaturescalled morgs. The squares encompass the remnants of Tombstone City'sdeteriorating cemetery, a safe area into which the morgs will notventure. The bottom of the display keeps track of the day, thepopulation (your score), and the number of remaining schooners. You can stop a game at any time and return to the skill selectiondisplay by pressing '''BACK'''. To start a game over with the same skilllevel, press '''REDO'''. ====Object of the Game====The object of the game is to score as many points as possible, while eliminating generating pairs of saguaros. The more points you score, the greater the population of Tombstone City. You start the game with a supply of 10 schooners. Play continues until the schooner supply is exhausted. A New Day begins when all morgs and all morg generators (pairs of saguaros) have been destroyed. Saguaros are destroyed when a missile hits a morg next to two adjacent saguaros. The schooner moves and fires horizontally and vertically. To move the schooner, press the arrow keys ↑ (E), ←(S),→(D), and ↓ (X) or '''I''' (UP), '''J''' (LEFT), '''K''' (RIGHT), '''M''' (DOWN). To fire the schooner's missile, press '''Q''', '''Y''', or '''ENTER'''. If the Wired Remote Controllers are used, move the lever to direct the schooner, and press the FIRE button to fire the schooner's missile. Position your schooner as rapidly and accurately as possible in order to fire its missile at morgs and tumbleweeds. If a morg is hit, it becomes a saguaro and adds points to your score. If a tumbleweed is hit, it disappears and also increases the score. Remember, morgs cannot enter the area of the blue squares. However, if a schooner is surrounded by saguaros while in this safe area, the schooner dies, and a new schooner (if any are left) is placed randomly outside the safe area. If your schooner is in danger of being attacked outside these borders and the area is not entirely surrounded by saguaros, press the '''SPACE BAR''', and the schooner reenters safe territory, and 1,000 points are deducted from your score. Normally, a morg is produced every 10 seconds. However, if you fire a missile and there are less than 10 tumbleweeds and no morgs left, a new morg is generated immediately. If a missile hits a morg next to two adjacent saguaros, these saguaros instantly become either one or two morgs, depending on the level of play. So be ready to fire again! ''Note:'' There is a limited amount of time to destroy any remaining morgs after all generating pairs of saguaro cactuses have been eliminated. If you find yourself in this limited time period, you must destroy the remaining morgs as fast as possible. Otherwise. the computer will time out, and you will have to restart by turning your computer off and then on again.
