Bioshock 2 - get Bioshock 1 free through Steam.
Title says it all really. Bioshock 2 comes out on the 9th of February, so buy it now and get Bioshock 1 for nothing for just £26.99. Which if you ask me is not bad at all even for a new game coming out let alone the first one free.
All done of course through Steam.
Not sure if this works for everyone but i would assume so.
