[UPDATE] Here is the official video:

The original story is below.

Today during a Twitch livestream, Injustice 2 developer NetherRealm revealed gameplay footage of the character Robin and others. This was captured by the YouTube channel GameplayOnly - Trailers & Gameplay and can be seen below. Batman also shows up in the trailer and you can see he has a new stance. Check out the full video below. We'll add an official version if/when it becomes available.

Also during the livestream, NetherRealm boss Ed Boon said there will be some somewhat obscure characters on the game's roster. The first Injustice game covered all the high points as it relates to well-known DC characters, with the sequel diving deeper into some new ones you may not know as much about. He also teased that there is good chance NetherRealm will release third-party characters as DLC for Injustice 2. He said these were very popular in Mortal Kombat X, so NetherRealm is doing it again.

Overall, Injustice 2 will have the largest roster for a NetherRealm game, both in terms of on-disc and DLC characters, Boon said.

Boon also made clear that Injustice 2 is taking steps to avoid allowing players to pay to win; gear will not be sold for money, he said.

Finally, he confirmed that codes for the Injustice 2 beta are going out now. The first wave has been sent out, with more to follow. You can find out more about the beta here.

Some of the other confirmed playable characters in Injustice 2 include Harley Quinn, Deadshot, Superman, Supergirl, Aquaman, Atrocitus, Gorilla Grodd, Blue Beetle, and Wonder Woman.

Injustice 2 launches on May 16 for PlayStation 4 and Xbox One.
