It looks like the Metal Gear Solid 5: Phantom Pain release date is going to be set after E3 2015 as reports indicate that the game would be showcased at the event.

Cyberland has reported that Konami would showcase Metal Gear Solid 5: Phantom Pain at the Entertainment Electronic Expo or E3 2015 on June 16.-18, 2015.

This report confirms that the release date of MGS 5: Phantom Pain would not come until after the event. It has been speculated that the release date would be announced at the event.

But why has it taken them so long to finish the game despite the number of gameplay videos officially released by the company?

Previously, we have reported that Hideo Kojima admitted that the game's production hasn't even been finished yet and that they're having troubles finishing it.

Gamepur has reported that play testing sessions have begun at the Kojima Station and that Hideo Kojima himself admitted that they are finding trouble on how to balance the game at the moment.

"The phase of adjustment takes place before the phase of difficulty setting or debugging. Putting together all the elements based on the plan. Checking like is it alright? is it fun?or good in balance? and fix those is the most important phase for action game. It's close to editing phase in term of film making but for game development this is the beginning of the main part." Says Hideo Kojima.

The report also mentions that:

"Kojima also talked about how tutorials are difficult this time. In a linear game you would start the player in a small area and gradually expand what they can do, but you can't do that in open world stealth. Ideally the player can go wherever he wants and can discover things himself."
