But then this is mortal kombat, so nothing has to make sense i guess :p
Just a word of advice, this part of the level is a complete pain, with the snakes and whatnot, so don't try this when you're at low health like we did, otherwise you'll end up being eaten by a tree like liu kang does (why not kung lao too? he's there as well tree!)
The test you have to pass in the middle of the green room is a lot of fun, and i used to be able to do it on my own without messing up, guess that shows how long it's been since i've played this game in any serious capacity, luckily i had a team mate to speed up the process a bit.
This video introduces the brutality, great if you want to kill people in a brutal way (duh) and works well against the orochi hellbeast, although when you're crowded with enemies and low on health i think a multality is much better, it clears the enemies away in one and you get a health boost into the bargin
