The game doesn't know if it wants to be a SHMUP, an on-rails shooter, or hack-n-slash. You have to play through the game AT LEAST three times to get the true ending, with the FIRST TWO play throughs being the same (it switches from characters 2B to 9S, but that's it). The story is cliché. The hack-n-slash combat is chaotic and thoughtless- just get good at pressing buttons really fast. The first lead character, 2B is your standard "hot girl with a bad attitude" we've seen so many times in other games.
