Most people initially thought that the reason why Dead Island 2 was taking so long to be ready was because the developers have actually abandon the game but that is not the case.
Deep Silver later reveal that the game is still being developed and that they have not killed it off yet. If that is true, why are taking so long to create the sequel to Dead Island?
Well, it might be because the game has been thrown from developers to developers but others think that there might be more to it. New reports are suggesting that the developers might have actually scrap whatever was done in the past and has decided to start fresh.
That means a new story as well as new mechanics for the game. That would certainly explain why we have not seen anything from the game even though it has been in development for some time.
