I should also check if there are any existing fan projects, but it's likely the user just wants a creative concept. They might not be aware that there's no actual Part 2, so clarifying that upfront is important to avoid misleading them.
Possible title variations: Apocalypto: The New Dawn, Apocalypto: Echoes of the Sky, or Apocalypto: Blood of the Jaguar. The feature should include setting, plot outline, character arcs, themes, visual style, and music. Also, note the disclaimer that it's a fan-created concept since there's no official sequel.
Themes like cultural preservation, leadership, and the clash between tradition and external threats are important. Characters like Jaguar Paw (the protagonist) could face new challenges, maybe dealing with internal dissent or external invaders. Including historical Maya elements like new cities, rituals, or alliances would add authenticity.
