While exploring the lowest level of the Shang Tsung's Lab Mesa in Season 2 of Invasions Mode, Mortal Kombat 1 players will likely come across the EHT GIB GNAK YROETH Klue. It can be found in the I'm Hip I'm Cool node near the Mesa's first Forge and rewards all those who are able to solve it with some pretty cool cosmetics and a few other useful items.
