I was asked to do this, so here you go, the parameters for the secret ending.
Now before you read any of this, I want to give you a fair warning, it's not very great. It's one of those feelsy warm-your-heart endings. It's not that hard, either, so for those who are confused enough at my scenario, which is understandable, here it goes!

So first, you need to check your abilities, and evolve all the way up to Omega_phase, then evolve the transmission "conscious.exe". From there, just infect the world and get a secret ending.
