It's been six months since the invasion of the Crescent Moon Squad Headquarters. The HQ has been rebuilt and expanded, and operations have resumed. After the success of your last mission, you received a promotion and some time off. Now it's time to get back to work.

A group of mercenaries code-named Apocalypse have been secretly developing three missiles each with enough power to wipe out a galaxy. Your mission is to enter their base, deactivate the missiles, and get out safely. Should anything go wrong, you must complete the mission, even if it means journeying across hostile lands, exploring dark caves, and fighting vicious monsters. The fate of the galaxy is at stake.

Good luck. You really are gonna need it this time.
