It certainly does feel that the visual novel genre has gotten the attention it deserves now that numerous titles like Clannad, Grisaia and Steins;Gate have been localised in recent years but now another popular visual novel series is also receiving the localisation treatment. Publisher Degica and developer Ixtl have announced their plans to release a kickstarter to localise the Muv Luv visual novels into English for Steam and other devices. The kickstarter is expected to launch sometime in late August-early September.
Due to Kickstarter rules the games will most likely be the All Ages version of the franchise.
The games included in the kickstarter are:
Muv-Luv Extra
Shirogane Takeru was living a peaceful life as a 3rd year high school student, with his childhood friend Kagami Sumika. However, one morning Takeru awakens to see a mysterious girl named Mitsurugi Meiya sleeping in his bed. Thus begins the start of a high school love comedy where Takeru will have to choose between his childhood friend and the girl insisting they are bonded by fate.
Muv-Luv Unlimited
Shirogane Takeru finds himself stuck in a parallel world where mankind is on the brink of destruction after battling against alien invaders known as BETA for the last 20 years. Takeru soon finds himself enrolled into the United Nation force to fight these aliens and finds the parallel versions of all of his high school friends, with the exception of Kagami Sumika, who does not seem to exist. Soon he will have to fight to save mankind, and protect the girl he comes to love over the course of the story.
Muv-Luv Alternative
Three years after witnessing the tragic exodus of mankind, Takeru wakes up believing that everything that had happened was just a dream. The brief hope that he has at last come back to his world is dashed away as soon as he discovers that he is once more trapped in the parallel world of Unlimited. Restarting on that fateful day he first came here, will Takeru manage to use his knowledge of previous events to change mankind's tragic future?
More information will be revealed at Anime Expo 2015 this weekend with the team attending in a conference with the Muv Luv Alternative: Total Eclipse creator Kouki Yoshimune and a couple other Japanese members who are involved with the production of the game.
