It seems Kojima is planning to show the E3 gameplay demo of Metal Gear Solid V: The Phantom Pain this Thursday, probably during the next Kojima Station episode. On Twitter, Kojima said:
E3 gameplay demo received much better than expected. It was closed-door & video shooting wasn’t allowed so it hasn’t been revealed yet.
TPP is free open world game, it’s hard to give u a presentation. The more u get hands on, the more u get to know such freedom & amusement. With that said, it’s disadvantage to show it in limited time at the show unlike Linear game that can be presented like a movie preview.
I shall ask Tan if he’s available Thursday to show off.
While it doesn’t look like it’s set in stone yet, there’s a good chance we will see at least part of the gameplay demo in the next Kojima Station, on Thursday. For those who don’t know, the ‘Tan’ Kojima is talking about is Tan Ziang, who also played the gameplay demo during E3.
Update: Kojima has now confirmed the whole 30 minute demo will be shown at Kojima Station:
Tomorrow at Kojima Station (7pm JPT), we will show you the actual MGSVTPP gameplay demo(PS4). Pls note the presentation will be in English.
TPP gameplay presentation (30mins) equivalent to what we showed in E3 that only 600-800 people had witnessed.Will be at Kojima Station tmrw!
Thursday’s episode of Kojima Station starts at 19:00 Japan time. The English episode is planned for June 20th.
