The team behind 2023 zombie romp Dead Island 2 has unveiled a bunch of new content for the title, and some of the biggest additions are available for standard edition players on Xbox Game Pass.

Basically, we're getting a major update that brings new content to the base game, while 'Gold Edition' owners are also being upgraded to a brand-new 'Ultimate Edition' with fresh content. The two big additions for base game players are New Game Plus and Horde Mode.

Dead Island 2's New Game Plus option adds "new zombie breeds, a boosted level cap & extra skill slots", while Horde Mode is a "brutal" way to play Dead Island 2 - you can "defend your frat house in the Venice canals", either solo or co-op.

As mentioned, those two major additions are free for all players, including those playing Dead Island 2 through Xbox Game Pass. If you happen to have the Gold Edition of the title (or are planning on picking it up), you'll now have a new Ultimate Edition to play with. Here, the game's existing story DLCs are being bundled with new character and weapon packs for the bumper Dead Island 2 experience.

Anyway, all of these goodies are out now for Dead Island 2 - and if you don't have Xbox Game Pass right now, the team has just added a brand-new free trial for anyone to try the game out!
