If they want to keep churning out more character packs and skins, they better make sure the game plays well enough to justify them. I’m honestly just happy to see NetherRealm continue to support the game and work on meaningful improvements. The cynic in me wants to say something snide about how they should have just gone with GGPO right off the bat, but I can’t.

Only four characters will be available to start (Scorpion, Sub-Zero, Jacqui Briggs, and Johnny), players will be expected to answer questionnaires about the game’s performance at the end of every session, and sign-up spots will be limited. And, while online play can never reproduce the completely lag-free experience of facing a friend sitting next to you, Injustice 2 helpfully includes delay simulation in its training mode options. But don’t expect to get too crazy: it seems like this is very much a test environment than a playground. Anyone who has spent at least an hour playing online in MKX is free to sign-up for a chance to participate in the beta on January 19 at (the site doesn’t seem to be active right now).

Think about the time scale under which this prediction is made: 60Hz. After listening to player feedback, the team is changing the way the game works online, switching from a “dynamic input latency model” to a roll-back system that (hopefully) more closely mimics the offline experience. NetherRealm is taking another stab at Mortal Kombat X‘s online performance.
