[UPDATE] This has all now been confirmed. The Dead Island Definitive Collection will launch on May 31 for PlayStation 4 and Xbox One. You can check out the announcement trailer below.

Deep Silver is promising higher quality textures, a "photorealistic" lighting system, physically based shading, image quality enhancements by way of anti-aliasing, improved game models and geometry assets, HBAO and other motion blur effects, and updated game UI. Additionally, the PS4 version makes uses of Remote Play and shareplay, as well as streaming and recording. All versions also have four-player online co-op.

Deep Silver also confirmed that the Power Firsts Power-Up mod will be available in both Dead Island and Riptide.

As for Retro Revenge, here is a quick rundown (courtesy of Deep Silver):

Retro look meets melee-based combat

Featuring leaderboards, achievements and plenty of depth

Game mechanics include power-ups, super attacks and a combo system

Finally, Deep Silver confirmed that the Definitive Collection will sell for $40. You can also buy each game's definitive edition individually for $20, but you won't get Retro Revenge. Deep Silver did not say if it plans to offer Retro Revenge as a standalone game outside of the Definitive Collection.

The original story is below.

It looks like Deep Silver is planning to re-release Dead Island and Dead Island Riptide on PlayStation 4 and Xbox One in a package that also includes a brand new standalone 16-bit game called Retro Revenge.

This information comes from retailer Best Buy, which has posted product pages for an unannounced Dead Island Definitive Collection for the new consoles (via Gematsu). According to the listings, it comes with the Dead Island Definitive Edition, Dead Island: Riptide Definitive Edition, and Dead Island: Retro Revenge.

The two definitive editions are "fully remastered" versions of the original last-generation games, complete with all DLC and patches, according to the listings.

As for Retro Revenge, here's how it's described: "A brand new standalone 16-bit game set in the style of a classic side-scrolling action/endless runner within the Dead Island universe."

Retro Revenge was first revealed earlier this year through a ratings board filing.

The release date for the Definitive Collection is listed as May 31 and the price is $40. We have contacted Deep Silver in an attempt to get more details, though this certainly sounds like the real deal.

Dead Island 2 was supposed to launch in 2015, but was later delayed to 2016. The zombie-killing game lost its developer, and we've still not heard which studio would be taking over for it. Dying Light producer Tymon Smektala has said in the past that he would love it if Techland returned to the series and got involved in the development of Dead Island 2. Techland was the developer of the original Dead Island.

The first Dead Island was released in 2011 with Riptide coming in 2013.
