With the recent rumblings of 2k Game including secuRom with the BioShock game disk a question was thrown to the officials over at official BioShock forums. You will not believe their response.
Jakester, a poster over at the official 2k Games forums, who was having problems installing the retail version of the game on his laptop kindly asked a question which went like this :
"I installed Bioshock on my laptop under one admin user, Everything works fine, but I then tried to switch users on my computer and whenever I launch Bioshock it is asking me to enter my serial again for the game…. Is this gonna charge me two of my activations ?"
