How many maps are in YAZS 1.0?

Steps

1. Start with Isolated City and advance through Vile Wasteland.
2. Continue to Green Hell, added as the third area, then Dead Terminal, added as the fourth.
3. Complete Dead Terminal on Default to unlock the fifth map, Bio Lab.

Requirements / Limits

• The developer guide's general rule is to win Default on the latest available map to open the next one.
• The 1.0 changelog names Dead Terminal on Default as Bio Lab's exact prerequisite.
• Map modes and difficulties unlock separately; owning all five maps does not open every mode on all five.

Common Mistakes

• Trusting the official community wiki's old revision, which predates the final three maps.
• Counting Camp as a combat map. It is the between-run hub, not one of the five arenas.
• Treating five main bosses as five extra maps; Boss Rush uses one main boss per arena.
