The worlds are divided into several zones, usually referred to by numbers. Thus, the first zone of the first world is 1-1, the first zone of the second world is 2-1 and vice versa. It would help if you kept in mind that until you complete 1-1, you cannot go to other worlds. Also, until you complete 2-3, 3-3, 4-3, or 5-3, you cannot go to 1-3. I would recommend following this order: • 1-1 (Gates of Boletaria) • 1-2 The Lord's Path) • 2-1 (Smithing Grounds) • 2-2 (The Tunnel City) • 2-3 (Underground Temple) • 3-1 (Prison of Hope) • 3-2 (Upper Latria) • 3-3 (The Ivory Tower) • 4-1 (Island Edge) • 4-2 (The Ritual Path) • 4-3 (Altar of Storms) • 5-1 (Deprived Chasm) • 5-2 (Swamp of Sorrow) • 5-3 (The Rotten Haven) • 1-3 (Inner Ward) • 1-4 (The King's Tower)
