Gantz:O (2016):

"After being brutally murdered in a subway station, a teen boy awakens to find himself resurrected by a strange computer named Gantz, and forced to fight a large force of invading aliens in Osaka."

Okay, so when you die, what happens? Odds are, you wouldn’t think you end up in an alien hunting ground where if you kill 100 aliens, you come back to life. Or are you really dead? Or just abducted by sadistic aliens that make you hunt for entertainment in high-tech battle suits? But, you keep flashing back to high school. And there they think you’re dead. This is Gantz:O, and it’s a weird movie with more plot twists than I just described and plenty of over-the-top action. It's on Netflix, so check it out.
