The Mighty No. 9 beta version received a brand new update today. Tier 2+ backers can now sample Mighty No. 2's underwater/ice stage. The update brings some additional polish to the core gameplay, too; steadier framerate and faster ledge grabbing, among other tweaks. I noticed Beck's model looks a bit smoother too.
Not a backer? No sweat! Check out the video above for a full walkthrough.
