Grand Theft Auto 4 is back on Steam and has been upgraded to the Complete Edition

As Rockstar announced last month, Grand Theft Auto 4 has returned to Steam, absent online components thanks to the removal of Games for Windows Live. The good news is that if you owned either GTA 4 or Liberty City Stories, you now own the Complete Edition, featuring the base game and the standlone DLC. 

The other versions were replaced by the Complete Edition yesterday, but save files are compatible if you had a game in progress. You won’t be able to hop into the multiplayer mode, however, which has been removed along with online leaderboards. RamJam FM, Self-Actualization FM and Vice City FM have also been taken out of the roster of radio stations.
