I don’t think any game has had as many trailers as Injustice 2, not even Mafia III, but each of these has either introduced new characters or a look at some of the systems in play. Today’s trailer is an amalgamation of everything that has been announced about Injustice 2, from the roster to the gear system, and Injustice 2 mobile.
The story will have three main factions in it as well as wildcard characters that aren’t aligned with anyone, for example Supergirl. But the story is only a part of the game and the real chunk of Injustice 2 looks like it resides in the Multiverse system and the multiplayer. The Multiverse has different areas all with their own rules, which can change daily, weekly, and monthly. Completing the multiverse challenges will unlock new Gear for your characters, which means their stats can be improved.
In online multiplayer you can create guilds with other players which will open up guild challenges, targets that have to be met together. You can also take your guild into fights and face off against others. Injustice 2 mobile has been improved over the original with better moves and character unlocks. Progress here can translate to the main game through Gear unlocks.
Injustice 2 will be available on May 19th for PS4 and Xbox One.
