Ubisoft has not yet announced a remake of Assassin's Creed IV: Black Flag, but fans have already found a number of (as they believe) proofs of its existence.
The fan community drew attention to information from j0nathan (@xJ0nathan). If this is not a mistake, then the AC IV: Black Flag remake is expected to include:
- Loot and stats system
- Combat system in the spirit of modern RPG games in the franchise
- Weather system in the style of AC: Shadows
- Loading screens will be removed
- The menu will be updated and the map will be improved (more details and activities).
It is also noted that "it was planned" that RPG aspects would play a major role, but their importance may have decreased during development.
