Ermac does not exist (Caemr oeds nto exists or w/e the scramble is)
Look to La Luna
Blocking will get you nowhere
Throwing Encouraged
Perfection is the key
In thinking maybe these are hints.
Maybe press the throw button or the 2 buttons to throw while looking @ the moon @ certain time
They're hints for sure, but they're hints from previous MK games....
Ermac does not exist was something from MK2 that referenced the rumor that Ermac was a hidden ninja in MK1.
Look to la luna was a reference to Reptile in MK1. You could only fight him if there was a silhouette flying over the moon during the fight.
Blocking will get you nowhere was another hint to unlock the fight with Reptile in MK1. You weren't allowed to block.
Throwing encouraged is simply a reference to a Kombat Code in MK3 where throws would have a little message each time you performed one.
Perfection is key is once again a reference to the Reptile fight from MK1. You had to double flawless with a Fatality when the silhouette flew by.
As much as I'd love for these to be references to some sort of fun secret in MK11, I'd be willing to be they're nothing more than some nostalgia for long time fans of the series. If there were something to discover, someone would have datamined it by now, I'm sure. As much as I hate the fact that there are rarely still secrets in NRS games, it's just the way it is.
Having said that Toasty Boost wasn't discovered until nearly 2 years after MK9's release, so there's still a small bit of hope.
