Suit up, you PC DC heroes: NetherRealm Studios have finally launched the online beta for Injustice 2‘s PC version. This beta runs from today (November 6th) to November 10th, and is open to anyone with a Steam account. As the beta is to test the PC network infrastructure and netcode, you can only play 1v1 matches during the beta’s run.

All stages and characters (up to Raiden) are available to play, so make sure to test out as many characters as possible during the beta. If you do experience any glitches or connection problems, make sure to leave your feedback via the Discussions page on Steam.
No news on when the eventual PC port of Injustice 2 is coming out, but based on what happened with Mortal Kombat XL, I would guess it will launch alongside the final character of Fighter Pack 3.
