Hideo Kojima has taken to Twitter to announce that PSone game Metal Gear Solid is included in the Metal Gear Solid HD Collection.
"Metal Gear HD series. The domestic version is a package of MGS2 and MGS3," he wrote.
"But, there is also a product code for MGS1, and MGS3 is subsistence specification, so MG1 and MG2 which were sold on MSX are included.
"This means, you can enjoy MG1, MG2, MGS1, MGS2 and MGS3 with this one!"
UPDATE: It appears MGS1 may only be included in the Japanese version of MGS HD Collection. We're checking with Konami UK now.
