BioShock: The Collection has been rated for PS4, Xbox One and PC by the Taiwanese ratings board.
The listing (pictured above) includes a piece of previously unseen artwork - possibly the game's boxart - which features both underwater city Rapture and city-in-the-sky Columbia, suggesting all three BioShock games could be being remastered for current-gen consoles.
The collection has yet to be announced by 2K, but has been rumoured multiple times. Back in September, a retail listing dated the collection for release last November. Then, in February, the game was rated by the Brazilian classifications board. The Brazilian rating also including listings for Xbox 360 and PS3, which do not appear to have been rated in Taiwan.
At the time of the game's original retail listing, 2K told VideoGamer.com that it "doesn't respond to rumours or speculation".
