Can this be downloaded if you don't have the game?

Yeah just found out you need disc. thanks cgi.
Might pick it up second hand as I actually never played it.
See what all the fuss is about.

IGN's closing comments: "Even in light of the claims made for The Lost and Damned, the sheer size of this expansion is staggering. GTA IV’s detractors may bemoan that what’s on offer is more of the same – while those enamoured with that game will be overjoyed at how much more of the same there is. Rockstar may, however, be a victim of its own ambition, as players hold up the content of The Lost and Damned to direct comparison with its forebear. Nevertheless, it’s a tale worth playing through and a welcome opportunity to once more step foot in the still magisterial Liberty City - and as an expansion it sets a new precedent for what’s possible with downloadable content at a price that makes it unmissable."

sums up everything i needed to hear about the dlc.

While the company's talent with stories suggests the day may be approaching when GTA runs up against the inevitable limits of openworld titles - a Scorsese-quality narrative

This game has me very excited now! People who complain about GTa4 and LATD must be blind to the huge leap of narrative quality Rockstar has brought to the franchise with GTA4 and now LATD. GTA4 and it's expansions are far above the PS2 titles due to their narrative maturation.

ive just read lost an damned has no extra city or streets. it plays in the same city as retail game but has another story to get through, with new charachters few vehicles and 3 more wepons..............i went into gamstation day and its advetised as if its a new game when it isnt, its dl content. but still it might be worth playing for xbox users. its somethin that i wouldnt spend cash on

Does it having to do with the gta4 story? wouldnt mibd meeting up with Packie and Brucie again!!!!!!

Doubtful, but you meet Niko (look at the 2nd trailer)
