Kojima Productions has confirmed that Metal Gear Solid 4's upcoming patch will include not just Trophy support but full install functionality as well.
While the Trophy support was confirmed earlier, the wording at the official site suggested that the install functionality would be limited to the game's package re-release. This is not the case.
Select to give the game a full install, and you won't have to wait between chapters for data to be cached to your system's hard disc. This lengthy caching, which was accompanied by an image of Solid Snake smoking, was a major complaint by players.
The budget re-release that includes the new functionality by default will be released in early August. The patch for current owners will also be offered around this time.
The game's assistant producer says the number of discs was an issue.
