The Grineer use the captured Warframe Chronos to go back in time to conquer the Earth. All the other factions lead an assault in order to stop them and in the end the Citadel crashes in to a city in 21st century Earth. Alan finds the Warframe Volt in the aftermath and must now deal with people whose ideals are backed by their Warframes, as well as other conspiring forces.

In the onset of the New War, Ouran is transferred to a special research unit after his continuous insubordination. But he wakes up in an unknown city with no memory of how he got there. He wanders the desolate city and is soon tasked to slay the mad Tenno with the mysterious exalted weapons. Forced to erase another Tenno's Oro, can he ever achieve the peace he is looking for?

I haven't check if anyone else did this but this is my version. Rating M for violence. SPOILERS for main quests. TLDR: Modern day Warframe battle royale. An entity of the void drags ten people from a modern day city in to a game for their lives. The winner is granted their deepest desire. Can one stay the same when given power? What does the demon gain by forcing them to fight?
