Up to now the two GTA 4 add-ons The Lost and Damned and The Ballad of Gay Tony have been Xbox 360 exclusive. But there is hope for the PC: First hints indicate a PC version.
GTA 4 - Screenshots of Episodes from Liberty City (110)
With Stories of Liberty City Rockstar published the two GTA 4 add-ons on a single disc. Now it might happen that The Lost and Damned and The Ballad of Gay Tony will be released for the PC, too. The two extensions offer more than the common DLC packs for other games.
Actually it has been expected that Rockstar would bring Episodes from Liberty City to the PC. But there is still no information about when this is going to happen. Now the first hints make PC gamers hope: The current Update for Games for windows Live contains Achievements for the first episode. Since this is unlikely to be a mistake one can expect that The Lost and Damned are to be announced soon. If this is really the case The Ballad of Gay Tony is more or less bound to follow, too.
In our gallery you can find several screenshots of the two add-ons that have been released.
