In the video game by Sega named Alien: Isolation, a certain room is named
“Left Hemisphere Overview,” and the corresponding Japanese text is 「 左ウィング・上x
」. The x symbol represents a kanji that I am having trouble identifying. Can
someone please provide the missing kanji? Here is the image:

question
kanji
“Left hemisphere (wing) overview” — 「 左ウィング・上x 」
It's 階{かい} that means floor (storey of a building). Coupled with the kanji
上{うえ} which means "above/up" etc is read 上階{じょうかい} and means "floor
above/upstairs". See all about it [here](http://kakijun.jp/page/1271200.html).
