· There are several unlockable modes, which you can earn by playing a Y*A*S*I* game and by scoring 1,000 points or more. The modes are:
A - Regular Y*A*S*I* game (default)
B - Guided missiles
C - Moving bunkers
D - Guided missiles and moving bunkers
E - Cloaking invaders
F - Guided missiles/cloaking invaders
G - Moving bunkers/cloaking invaders
H - Guided missiles/Moving bunkers/Cloaking invaders
Several modes can be unlocked during a single game, as long as a multiple of 1,000 points are scored (it’s believed with the final mode – H - you have to score several thousand points to unlock it). The modes can be selected from the main Y*A*S*I* menu by pressing the #2 button. Erasing the high scores (from the main menu) will erase the modes and you'll have to start all over to unlock them again by playing again. {Darryl Brundage}
