The latest updates for "Destiny 2" will feature new combat, sub classes and skill tree, as well as two add-ons on its DLC expansions.

It seems that Bungie will be revealing new game details for "Destiny 2" on May 18, but gaming fans are still curious as to what the game developers have in mind when they showcased the sequel next month.

Some of them have made their own theories and speculations regarding "Destiny 2's" new game features. One of the many theories is the combat system in "Destiny 2" as Bungie plans to handle classes and abilities in the game.

From the game’s marketing materials players already know that Hunters, Titans, and Warlocks will be making a return to "Destiny 2," but whether or not they will have the same, similar, or completely new abilities is still unclear.

Luckily, the tweet from "Destiny" Twitter page hinted that gamers will earn all new weaponry, combat abilities and a whole ton of new loots.

It has been hinted that gamers will likely expect a new Guardian class and sub-classes in "Destiny 2" a deeper, more RPG-focused class system that really makes each character feel unique. Having one subclass means more customization options.

Another popular theory is that "Destiny 2" will are new sub-classes and they are based on new elemental concepts. Decay has been an idea tossed around for a while now in the "Destiny" community, and perhaps something similar could make its way into the sequel.

There are also hints that Bungie could rework the combat system to be less subclass based and it will be something new and less element-based.

Gaming fans are also interested to see "Destiny 2" go for a more freeform RPG experience, offering players a single, more expansive skill tree, Gamerant reported.

In other news, Bungie teased that two of Destiny 2's " expansion DLC packs will feature the Osiris and Rasputin add-on, GamingBolt reported.

Osiris was supposed to play a major part in the original "Destiny’s" story, but ultimately did not make the cut, and there is a lot of interesting lore surrounding Rasputin as well, so it will be good to see them being included in "Destiny 2."

In addition, there is also a leaked fact sheet suggesting like the first game, "Destiny 2" will release its first DLC expansion in the winter of 2017 and a second one in the spring of 2018.

"Destiny 2" will be available on Sept. 8 for the PS4, Xbox One and PC platforms.
