So i'll leave a short review since i don't want to spoil much

First of all, how was the localisation? Pretty damn good, they've re-done the translation completely and have managed to capture the character kinks and speech charms a lot better than the original translation, they've also included extra CG's for certain scenes and extra dialouge here and there making it a much better experience, and the upgraded engine making it run smoother. along with every diagram/map being fully translated it helps you understand what's going on better.

Next i'll just give my opinion on alternative itself

It is, without a doubt, the best Visual novel on the market (That's been translated) that i have ever read
You DO need to have read most of the routes of Extra and at least 1 of Unlimited to enjoy this, it's a part 3 to Muv-Luv's first two parts

The story is incredible, it takes what you thought you knew about the betaverse of the series and blows it all away, nothing you learned in the first two VN's is entirely accurate, there are many secrets yet uncovered and many points of developments to be had.

The strongest point of Alternative is most definitely it's character development, whilst the characters themselves may be fittable in to the standard Archetypes, the way they're made to interact with the expansive world and other characters plus the inceredibly intruguing events that take place in this VN breathes life in to them, i've heard people saying that having only one route makes this VN bad, however you should not look at it this way, Alternative does not have 'one route', it is a single story with one outcome, The characters develop together and better themselves through debate, conflict, sorrow and such forth, unlike route based novels where the development is lopsided, everyone develops together.
Also on this note, the main character does not suffer from the self-insert problem that most vn's suffer from, in fact he is the most amazing source of character development throughout this novel.

Anyway, the novel deals with some heavy topics such as general ethics, patriotism, politics, coping, ptsd and many more in an absolutely beautiful way, this isn't some ♥♥♥♥♥♥ Eroge nor is it a Kusoge, if you think it's either you're simply reading it wrong.

Most of this was just rambling, but this was my 6th time reading this novel through and i'm glad that i backed it when i did, our folks over at the Muv Luv Team did an amazing job bringing such a great localisation to us in such a short time for a VN this length, and they even managed to dodge the censor bullet that most Steam releases fall to (I mean, yeah there's no explicitally r-18 scenes however most scenes were completely uncensored apart from the 2 original h-scenes which were basically just given a new CG that displayed less and had the text remain mostly the same, which is great)
