Rank War Stages

A stage (ステージ) or MAP (マップ) is a virtual arena in which Rank Wars are fought. It is selected by the lowest-ranked Squad competing in a match and revealed a few minutes before its start.

Settings
Stages appear to be set by default to daytime and calm weather. However, the Squad which selects the map can freely alter the time of day and weather conditions, which will not be known to the opponents and spectators until the match begins. Changing the setting of the map is rare in general has only 3 out of the 9 Rounds shown have unique settings which makes sense as everyone is affected by the change. Extreme settings are generally avoided, as they make placement luck all the more important as well as the previous point.

Night
This setting makes it so the combatants have to keep night vision on which can be coupled with areas with bright lights like Cityscape D.

Rainstorm
The only known extreme weather setting, This makes navigating the terrain harder as every outside is wet, this setting has also been shown to affect areas with pre-existing water areas like Riverside A.

Snow
The only known normal weather setting, the snow is about 30 centimeters deep which heavily limits mobility for people without grasshopper however it is possible to bypass this by running on walls.

Trivia

 * In Chapter 87 the preview images are shown of what appear to be a forest stage and a map similar to Riverside A, but with a different, smaller bridge.
 * At least one session of stealth and target acquisition training took place in a ravaged urban area.
 * The preview image of Industrial Area has a nighttime setting.
 * There is a open field mentioned by Kazuaki Ōji in Chapter 150 which may be part of the Exhibition Hall.
 * In the original Japanese release of Chapter 152, Osamu appears to be initially unaware of what stage he has just spawned in, despite maps being revealed a few minutes ahead of the match. This was fixed in the volume version, although the error persisted in the English release.
