"A destiny tossed about, in an insane world---
A flame of life blazing forth, in a dying world---
And now, one more future that is spun---
This is the alternative ending unable to be told before:
A very great, a very tiny, a very precious...
Tale of love and courage." (The next part has spoilers, so beware!)
Three years have passed since the day Takeru, an unsuspecting Japanese high-schooler, suddenly awoke in a world not his own — a war-torn alternate reality in which mankind was on the brink of extinction, locked in a decades-long struggle against the ruthless extra-terrestrial invaders known only as the BETA. In that time, he’s been through an awful lot — enlisting in the military, meeting parallel-universe versions of his old friends, and even falling in love. But unbeknownst to Takeru, he and his squadmates were being trained to participate in a top-secret UN contingency plan known as Alternative IV — a last-ditch effort to take back the Earth via experimental technology. Unfortunately, however, development screeched to a halt when the project’s chief executive, Professor Kouzuki, hit a wall in her research due to technological constraints. With tensions rising, and pressure to shift gears from governments all across the world, the UN delegation opted to scrap the project in favor of its successor: Alternative V. This was humanity’s last resort — a plan that utilized all of their remaining resources to build a migrant fleet of interstellar craft, allowing a tiny fraction of the population to abandon the Earth in the hopes of finding life anew in another star system. Takeru and his comrades-in-arms were among those left behind, condemned to death by their fellow man.
But it seems the hand of fate has bigger plans for Takeru, because it’s at this point that he wakes up to find himself back in his childhood bedroom once again. Not in his own world, mind you — but back where he was first spat out into this hellscape three years prior. This was no dream; this was a recurring nightmare. But then it hits him: this is a second chance. If he’s truly been sent back in time, then he’s the only one who knows of the impending doom that awaits this world. Perhaps he can use this knowledge warn to Professor Kouzuki, and together, they can somehow find a way to prevent Alternative V from ever being enacted. And who knows? If he can change history, then maybe — just maybe — he’ll find the answers to all of his questions. Why has he gone back in time? Why isn’t Sumika here? And most importantly, what IS Alternative IV?
Muv-Luv Alternative continues the story of Shirogane Takeru after the events of the original Muv-Luv. This is a tale of a love so deep it breaks all barriers; about courage in the face of adversity and overcoming hardships. Takeru encounters and conquers insurmountable odds while his entire world is turned upside down around him.
Ending Guideline / Suggested Ending Order
Muv-Luv Alternative has 5 endings and 19 Steam achievements to unlock. By following this guide you’ll able to see and unlock all of them. Be mindful that the list below contains spoilers and you’ll also unlock all CGs as you go. This game requires five playthroughs to get all the achievements, but thankfully, there is chapter select, so as long as you do the first playthrough correctly, you won't have to restart the game from the very beginning. The recommended ending order is:
Kasumi --> Chizuru --> Kei --> Miki --> Mikoto
It is more optimal to do Kasumi's ending first, since, in the next playthroughs you can use a chapter select shortcut (the other "routes" also require fewer choices).
It is advised to save before making any choice. Notes were left inside the spoiler boxes in-case you follow the recommended order. The method that is written outside the spoiler box may only work for the XBOX version!
After clearing playthrough 1, go to Chapter Select, and click the fourth option under chapter 7. Auto-skip and choose "Class Rep" 2 times. Then just pick whatever choices you like, and finish the game. Auto-skip again is probably a good route to go for this.
After clearing playthrough 2, go to Chapter Select, and click the fourth option under chapter 7. Auto-skip and choose "Ayamine" 2 times. Then just pick whatever choices you like, and finish the game. Again, auto-skip is best, unless you want to play it again.
After clearing playthrough 3, go to Chapter Select, and click the fourth option under chapter 7. Auto-skip and choose "Tama" 2 times. Then just pick whatever choices you like, and finish the game. Again, auto-skip is best, unless you want to play it again.
After clearing playthrough 4, go to Chapter Select, and click the fourth option under chapter 7. Auto-skip and choose "Mikoto" 2 times. Then just pick whatever choices you like, and finish the game. Again, auto-skip is best, unless you want to play it again.
