So since I am intrigued to see if Boon is telling the truth
I went through this video.
First of all I don't know if you guys noiced this but at 0:35 if you play it back slowly you can see an item actually highlights in the background behind Scorpion. I also noticed branches randomly start emanating cold air / frost too. Not sure if this is part of the stage or a way to say Sub Zero can use the stage.
0:34 - Scorpion jumps on a branch and swing kicks Sub Zero.
0:52 - Bug Lady uses the wall to jump over to other side of the arena. Uses Pot as projectile.
1:05 - Scorpion presumably uses a tree stump to jump to branch of tree and move to other side of screen
1:09 - Scorpion grabs tree and uses it to launch X-Ray attack against Sub Zero
1:17 - Bug Lady swing kicks Big Dude
1:20 - Big Dude grabs body from sea and throws it at Bug Lady
So there's a mix, but I am a bit worried now. I mean yeah the offensive interactables are easily blocked but it still seems a bit unbalanced.
I've included some shitty captures to show what I mean.
In the images above you can see something (?), a pot and a tree stump all highlighted.
