Splatoon - So basically...

I got some Portal vibes from the elevator part before the final boss.

I mean, test chambers? Check
AI tries to kill you after finishing tests? Check
An escape sequence after that? Check
And final boss with AI that invovles running around it and doesn't involve direct combat? Check.
Also the boss is on a set timer
So the resmblence is there for pretty much the entire campaign lol
