It seems that data miner X-Kira is on a roll as of late. Recently, they had uncovered evidence of a working arcade mode, and other costumes and stages in Street Fighter V. However, that’s not yet the full extent of what they’ve found — it seems that they’ve now found evidence of a bonus stage in the game as well.

Specifically, the data in question seems to be for the classic falling barrels bonus stage from Street Fighter II and Super Street Fighter IV. The bonus stage itself isn’t playable in any form as of yet, however, as the video below shows, files and references to it exist in the games code.
