Mission 660 (bootleg) — About this game
Mission 660 (bootleg) is an exact registered version in this game family. Mission 660 sends the player’s spacecraft through changing waves of enemy ships. Sustained firing clears formations before the larger ship arrives, where several hits are needed to finish the encounter. Defeating it starts another cycle. Alongside ordinary fighters, unusual mouse, cat and skull shapes make the next target’s movement worth watching rather than assuming every wave behaves alike. Version-specific changes to characters, stages, timing, difficulty, balance, graphics or hidden content are not inferred where the registration does not document them.
