Muv Luv

The gameplay in Muv-Luv requires little player interaction as most time is spent reading the text that appears on the lower portion of the screen, representing either dialogue between characters, narration, or the inner thoughts of the player character. Every so often, the player will arrive at a "decision point", and be required to choose between multiple options. Gameplay pauses and depending upon the player's choice, the plot will develop in a specific direction. There are multiple plot lines that the player can follow, one for each heroine in the story, and there are nineteen possible endings.

To view all plot lines, the player must replay the game multiple times. The game can end in failure if the player makes the wrong decisions. When this occurs, the player can return to a previously saved spot to try again.

The visual novel Muv-Luv is divided into two parts. The first part, titled Muv-Luv Extra, features playable character Takeru Shirogane (voiced by Sōichirō Hoshi, credited as Tsuyoshi Aiba in the Windows version) who wakes up one morning to find a beautiful young woman sleeping in his bed, just as an infuriated Sumika Kagami (voiced by Hiroko Taguchi, credited as Rika Fujiwara in the Windows version), Takeru's neighbor and childhood friend, comes to wake him up that morning. The young woman, Meiya Mitsurugi (voiced by Kazumi Okushima, credited as Aki Okuda in the Windows version), is the heiress to a financially powerful family and is determined to be Takeru's bride. As the story progresses, both girls compete for Takeru's affections while Takeru has recurring dreams about a marriage promise he made to a girl long ago.

At first, he believes the girl was Sumika, but eventually realizes that it was actually Meiya. At the conclusion, Takeru must choose between which of the girls he truly loves. In addition, the player may also make decisions to choose between one of the three girls in the main supporting cast: Chizuru Sakaki (voiced by Masayo Kurata), Miki Tamase (voiced by Hitomi), and Kei Ayamine (voiced by Yūko Nagashima).
