A city before it becomes a battlefield
The campaign stays with Kalona through the opening invasion rather than turning the whole planet into a travel itinerary. The developers describe the city through ordinary peacetime details: veterans returning home, recruitment messaging, shops and older television technology. Those details give the destruction a human scale.[3][4]

City Hall, Oria Stadium and the waterfront
The city includes an industrial waterfront, refineries and surrounding housing, a stadium and an airfield. Its coastal setting draws on the developers’ experience of Vancouver. The Coalition explicitly describes the campaign as not open world, even though Kalona is designed to feel like a connected city.[3]
| Location | Role in the preview |
|---|---|
| City Hall | COG command and medical base; Bravo assembles for briefing. |
| Oria Stadium | Forward operating base; Bravo meets Tai and Theta Squad in Act 2, Chapter 2. |
| Rail station | Objective reached after leaving the stadium; the demo ends after the fight here. |
During Act 2, public buildings become military infrastructure: City Hall hosts command and medical teams, while Oria Stadium serves as a forward operating base. Bravo then pushes toward the rail station.[3][5]
At City Hall, Colonel Trench directs the military response while the mayor argues for civilians. Captain Akila Grey registers Bravo's details. The COG command guide explains those roles; at Oria Stadium, Tai and Theta Squad connect Bravo with other defenders.[5]
The historic Golden Quarter is a Horde Siege battleground. Its older architecture, shown at the top of this page, gives the shared squad missions a different setting from the industrial waterfront.[1]
The same setting, different map functions
| Experience | What has been announced | What you do there |
|---|---|---|
| Campaign | A story in Kalona across three days | Follow Bravo’s story through the opening invasion. |
| Horde Siege | Three launch maps; Golden Quarter shown | Large shared battlegrounds support squad missions. |
| Versus | Outpost, Battleship, Park, Precinct, Market, Skyward | Six competitive maps in and around the city. |

The Versus maps move between military, commercial and residential spaces. Precinct uses tight police-station interiors, Market combines longer streets with balconies, and Skyward connects exposed rooftop routes.[1]
Is there an official city map?
Bravo uses a tourist pamphlet as an improvised in-game map. A civilian guide becomes a way for the squad to find its route through a city suddenly at war.[5]
Is Kalona an open world?
No. E-Day has a story campaign with connected spaces and opportunities to take different routes through encounters. Kalona is the campaign’s setting rather than an open-world map.[3][5]
For the multiplayer objectives that take place in these spaces, use the Horde Siege mission guide or the Versus mode comparison.
