8 Bit Tower Defense Worlds List: Every Story World in Order
All 6 story worlds in 8 Bit Tower Defense in campaign order — from Greenfield Outpost to the Hollow King's Ashen Citadel — with each world's unlock requirement and how to see which act is next.
Quick answer
8 Bit Tower Defense has 6 story worlds. The campaign starts at Greenfield Outpost and ends at the Hollow King's Ashen Citadel, and each world is split into 6 acts. Clearing a world's Act 6 unlocks the next world, and the Play menu's STORY section shows the full world list with your progress and every unlock requirement.
- Campaign order: Greenfield Outpost, Sakura Shrine, Dustbowl Canyon, Frostbite Pass, a fifth world the reviewed footage doesn't name, then Ashen Citadel as the finale — six worlds in all.
- Each world has 6 acts — clearing Act 6 unlocks the next world.
- To see which world is next, open STORY in the Play menu: locked entries print their unlock requirement, and the world you are clearing shows act progress like Act 2/6. Your next battle is the first act you have not cleared on the furthest world you have unlocked; press Play to start it.
Every story world in campaign order
The official game description gives 8 Bit Tower Defense 6 story worlds, from Greenfield Outpost to the Hollow King's Ashen Citadel. They follow a fixed campaign order, and each world gates the one after it:

Four of those names and their exact unlock texts come straight off the in-game menu, and the two ends of the campaign come from the official game description. One world isn't named on this page: the reviewed menu capture reaches Ashen Citadel without showing the entry that follows Frostbite Pass. The shape of the campaign is certain either way — six worlds, Greenfield Outpost first, Ashen Citadel last, everything in between unlocking in sequence. When you reach the finale, the Ashen Citadel guide covers that world in detail.
How each world unlocks
Every world contains 6 acts, and the same rule carries you up the whole list: clear a world's Act 6 and the next world unlocks. Locked worlds print the requirement right on their menu entry — Sakura Shrine reads "Clear Greenfield Outpost Act 6 to unlock", Dustbowl Canyon reads "Clear Sakura Shrine Act 6 to unlock", and Frostbite Pass reads "Clear Dustbowl Canyon Act 6 to unlock".
A world you are already working through shows progress instead of a lock. In the captured menu, Greenfield Outpost displayed "Act 2/6", showing at a glance how far into its six acts that run had reached.
How to see which world and act is next
The Play menu's STORY entry lists the worlds in campaign order, and each entry states its condition: either a lock you have not met yet ("Clear ... Act 6 to unlock") or act progress on the world you are currently clearing ("Act 2/6"). The next world is simply the first locked entry ahead of your progress.
For act-level detail, open the Story tab from the Play menu. It lists every world and act so you can pick your next battle — a cleared act opens the next one, and pressing Play starts the selected act. So the answer to "what's next" is always the first act you have not cleared, on the furthest world you have unlocked. For a fuller walkthrough of the acts themselves, see the story mode guide.
Story progress also gates the other modes
The Play menu lists the other modes right alongside STORY, and several of their unlock requirements are story-world progress, so the campaign order matters beyond Story itself:
- RAIDS — "Clear Ashen Citadel", which means finishing the entire story campaign. Details in the raids guide.
- EXPEDITION — "Reach World 2 Act 4", i.e. Sakura Shrine Act 4. Details in the expedition guide.
- CHALLENGES — "Reach World 1 Act 6", i.e. reaching Act 6 of Greenfield Outpost. Details in the challenges guide.
- WORLD BOSS — "Clear Greenfield Outpost Act 3 to face the Tide Titan". Details in the bosses guide.
Knowing where you sit in the world list therefore tells you more than which act to queue next — it shows which modes are about to open up. The game modes overview puts all of them side by side.
