>>705935If you start MuvLuv Extra, you get a regular high school comedy romance VN. If you get Sumika and Meiya's endings, the starting menu changes and lets you start Unlimited. This is the mecha school VN, with the same characters but in an alternate history setting (more or less).
MuvLuv Alternative is a separate VN but takes place in the same world as Unlimited and you are expected to at least have basic knowledge of Unlimited as it is effectively a sequel.
btw I'm trying to step around spoilers, sorry if I'm being a little too vague.
