So before I get into this, there are a couple things I'd like to clarify for those who are unaware. Muv-Luv is a 3-part visual novel series released between 2002 and 2006, the last part of which, Muv-Luv Alternative, is widely considered to be one of the greatest visual novels ever made. However, ever since its release now 10 years ago, the company behind it, Age, have done literally nothing other than create a myriad of side stories, spinoffs and fandiscs based on the Muv-Luv universe. They've never even tried to come up with a new franchise for a whole decade now, instead they've decided to just keep milking their one and only masterpiece until it can be milked no more, which is... understandable I guess, but still pretty saddening. In any case, the Muv-Luv trilogy has never gotten an anime adaptation and perhaps never will, but in 2012 there was actually an anime release... based on one of its countless spinoffs called Total Eclipse. Not only was this a rather strange decision since any anime-only viewers would miss out on tons of plot elements due to being unfamiliar with the main series, but also Total Eclipse turned out to be an incredibly mediocre anime in and of itself, focusing just as much on fanservice as actual story progression, if not more. And now, 4 years later, history repeats itself, as yet another one of the franchise's spinoffs has gotten adapted, namely Schwarzesmarken. But of course for any anime-only viewers, the exact same problems as last time still remain.
The good news however is that the story of Schwarzesmarken is largely separate from the one of the main story of Muv-Luv. This is because a) it's a prequel, taking place almost 20 years before the events of Alternative, b) the character cast is completely different, and c) it plays out on the other side of the planet, in Germany instead of Japan. So in that sense it works out fairly well as a standalone anime... but far from perfectly. This is because Schwarzesmarken intentionally leaves out just about all initial exposition about the state of the world itself, any detailed information about the BETA's functionalities and tendencies, as well as a lot of the planet's history ever since the BETA's initial sightings on Mars in 1958 and their eventual invasion of Earth in 1973. And this is all simply because the anime assumes that you already know all that from playing through Alternative. So it's not that the story won't make sense for anime-only viewers (it will), but you'll miss out on a lot of depth and detail. It also works the other way around as you'll be able to relate a lot more to events which have previously only been mentioned briefly in Alternative as it plays out in real time here instead of something which just happened far away and almost 20 years prior from the game's perspective.
Overall though, Schwarzesmarken is still a pretty big improvement over Total Eclipse at the very least. The tone is a lot more on point with what Muv-Luv is supposed to feel like, with a lot of death, drama, politics and tragic events (though not as much sci-fi). There is also pretty much no fanservice at all this time around which I'm very thankful for. So atmosphere-wise Schwarzesmarken is a lot more similar to the main series, but there are still some clear differences. The most notable one would probably be the direction the plot goes in, and specifically who the real enemies in the story are. In the main series, it's naturally the BETA that everyone is fighting since humanity's mere existence is on the line, but in Schwarzesmarken they almost feel like the secondary threat a lot of the time. Of course there are still a lot of battles between the human TSF squadrons and their alien invaders, but in this case there seems to be just as much internal conflict as external. This is because this takes place in Germany in the early 1980s, which of course means that it's in the middle of the country's split in two, I.E: West Germany and East Germany. The squadron the story primarily follows is the East German Army's 666th TSF Squadron, a.k.a. the "Schwarzesmarken". They do their part in fighting the BETA on a daily basis, but they see their western neighbors as just as much of a potential threat as the aliens themselves, and the west is of a similar mindset. It's almost like a three-way war going on, except that the two human sides are having more of a cold war standoff and throwing insults at each other most of the time, but occasionally end up clashing head-on as well. This is unsurprisingly also used as a consistent and reliable method for generating drama, as some characters find themselves on different political sides despite caring for each other on a personal level. And on top of that there's also the good old truth that killing off main characters is not exactly something Muv-Luv has ever been afraid to do, and although it might not exactly be on the level of the main series, Schwarzesmarken is still not afraid to do the same. It gives the post-apocalyptic story a much greater sense of realism and intensity that way, and it definitely pays off.
Schwarzesmarken is definitely not a bad anime by any means, but I still find it a bit difficult to actually recommend it to people. Because if you haven't played through the Muv-Luv trilogy prior to it, then you should definitely go do that first, and if you have played through it then try as you might but you'll find that it's almost impossible to not end up subconsciously comparing Schwarzesmarken to the main series as you're watching it. There will constantly be this nagging voice in the back of your head saying "I wish I was just replaying the real game instead". Schwarzesmarken isn't bad, but just by being part of the Muv-Luv universe the expectations on it will be so much higher than it ever has a chance of living up to, and Alternative is just such an incredible work of art that Schwarzesmarken ends up looking a lot worse than it actually is simply by being compared to something so unreasonable. I think the only way you can truly see Schwarzesmarken for what it is is by first playing through the visual novels and then literally forcing yourself to go into the anime with the lowest expectations possible. If you tell yourself prematurely that it's probably going to suck, then you might be positively surprised. But if you don't, you'll probably just be disappointed.
Though pretty much all these problems would be solved if Age just decided to actually adapt the real Muv-Luv series already... which I've actually heard some rumors as of late that it might happen in the future after Alternative's localization Kickstarter project turned out to be such a huge success a few months ago. Maybe in another 5-10 years, who knows. One can only hope.
