The latest installment in Broccoli's bishoujo sci-fi/comedy series is coming out on the 18th of next month. It combines adventure/dating-sim parts with real-time space combat. The series seems to be really popular in Japan, so in an effort to milk this for all it's worth Broccoli will be releasing two limited editions, an expensive and an even more expensive one, with MSRPs of 9,975 yen and 13,440 yen respectively.
