I was just thinking, wouldn't be cool if they hid some information in the beta that were clues on how to unlock the hidden characters within the Beta event?
Like if Smoke is a hidden, or Reptile or Noob... Have them drop in before a match and give us a clue like Mk1-3.
Or have certain intro dialogue that only appears in the beta that hints to Shang Tsung or one of the other hidden.
Sub Zero to Raiden "I thought you said Shang Tsung was no longer a threat"
Raiden "Kronika, Goddess of Time is responsible"
Sub Zero "You God's are losing my faith"
Or Sonya to Raiden
"Hey Thunder God, make it Rain?"
Raiden "that will cost extra"
Sonya "Rain is DLC?"
What do you guys think?
