Dead Island 2 Leaked Demo
Dead Island 2 had been delayed for over 5 years. On Twitter, a user with the handle @GarnetSunset tweeted out that a playable dev from 2015 has leaked.

Dead Island 2 was originally scheduled for a Q2 2015 release but has been delayed after a series of developers leaving Deep Silver and transitioning the development of the game to Dambuster Studios, an internal studio in Deep Silver.
The game is a survival horror RPG, a sequel to Dead Island which came out in 2011. Taking place in California, the game has several new features from its predecessors.
