When was dead island 2 announced?

Dead Island 2 was announced by its developer, Yager Development, during Sony’s E3 2014 press conference. A cinematic trailer for the game was shown, but no release date was announced at that time. However, the development of Dead Island 2 has faced several setbacks, including changes in the development team and delays, and the game’s release date has been pushed back several times. As of my knowledge cutoff in September 2021, the current release date for Dead Island 2 has not been officially announced.
