The PS3 version of BioShock has a 5Gb mandatory install that takes a little over 10 minutes to complete.
While the game's trundling onto your hard drive, your TV shows your Rapture ads and plays a little piano music.
The game was rumoured to have a sizable install after the BBFC rated the game back in July, but 2K commented at the time that it was likely to have an install of “around 5 or 6 minutes” at most, according to this DarkZero report.
The news comes from the new Eurogamer playtest we linked to earlier.
BioShock releases for PS3 on October 24.
