I'm pretty sure it isn't. 'Level 16' sounds more like a made-up concept for entertainment rather than being based on actual events. It's likely to have been crafted purely from the imagination of the creators.
Level 16 is purely fictional. The plot and characters are crafted by the writer's imagination to tell an engaging story rather than being based on real events.
Definitely not. 'Level 16' is a work of fiction. The filmmakers came up with the story and its elements from their imagination, not from any real events or people.
I'm not sure specifically what 'level 16 based on true story' is about without more context. It could be a movie, a game level, or some other form of media that is based on real - life events.
