ok like everyone else I don’t have much to go on. I saw a trailer a few months  back about a teenage to wakes up to a totally ruined city scape almost like an apocalypse don’t know if he was frozen underground or summat. he climbs out into this city and sees a giant robot/mech and he runs into some girls who seems to have some idea about what’s going on asks him and she says he doesn’t have a clue. Anyway the bots seem to have taken over and there is one human city that is powerful enough to keep the robots out. sounds like the matrix or maze runner-ish but it’s not. it looks like sci fi fantasy got a feeling it was based on a book.
