Rampart is the final Mesa in Season 2 of Invasions Mode and also the home of three thought-provoking Klues. The first of these can be found in the Get Up node and presents Mortal Kombat 1 players with a series of letters and digits. At first, it all seems a bit like jibberish, but it's actually fairly simple once players take a step back. Instead of looking at what's there, they should instead look at what is missing, which will lead them to the real clue: C4.
