Kinda hope that it returns to Xbox soon, they have it as a recommended game atm but still unable to purchase :-( with them announcing MGS GZ the other day which looks incredible (although lets hope it has a bit more gameplay than 4) really want to check
this one out. The PSP exclusive are the only ones I`ve missed out on
I think it got pulled because there were some major technical issues. A day one patch seemed to break the game entirely, it was hardlocking people's consoles when it started up, so I guess they took it all down to fix it.
