PizzaWolf112-I don't have any idea about what versions. I only just heard about it. I first saw something about it when I was in the Discussion page on SkyDoesMinecraft's channel just a few hours ago, looking for answers on why he went from 10M subs to back to 9M (YouTube deleted inactive channels, BTW). I accidentally bumped into a conversation about Entity 303, and that's where I learned about it. Looking for more information, I looked it up on YouTube and found a video that explained his dreadful plan. It didn't really explain what versions he was attacking, but it did give some tips on how to make sure he doesn't attack your worlds. But when reading the conversation, I did find something......
This is what the user "TheCodedProgram Gaming, Nature, Tutorials, and More!" said:
"Adam, are you aware of Entity 303? A fired employee of Mojang has recently stated the infection of the future of Minecraft. He's saying that Entity 303 is ten to twenty times worse than Herobrine. Is he saying that Herobrine has been alive all these years and he just never saw us? I've noticed that Herobrine sightings have been more rapid. He doesn't know how to communicate. The only word he commonly uses is 'hjalp' which means help in Swedish. This makes sense, due to the fact that Minecraft origins were of course in Sweden. Herobrine has and never was evil. Nowhere in the original sighting of Herobrine did he ever say he attacked. He needs our help. Every video one of you viewers see of him 'attacking' is fake. Please spread the word. 'He's looking out for you. Trying to warn you of the dangers you can't see.'"
Does this mean that Herobrine never was evil, like this guy said? Is he going to help us fight Entity 303? But more importantly, who IS Herobrine really? How come Notch has denied there being a Herobrine, but one of his ex employees says there was a Herobrine? Later on in the conversation, the same guy says:
"I have never seen Herobrine, but Entity 303 only appears due to Herobrine, so Herobrine has been in my game. Entity 303 destroys everything. He is 5623x more powerful than Herobrine!"
"Only us, Sky, Swimmingbird, and another guy knows. Lets keep it that way, so it isn't viral for the love of Minecraft."
These two posts were his latest posts on this conversation. I'm just surprised that I haven't seen anyone on the SA forums talk about Entity 303, since they are plenty of Minecraft lovers here. Hopefully, Entity 303 can be stopped, and we can learn more about the mysterious player called "Herobrine" and his real intentions. Spread the word. We must stop Entity 303, or Minecraft will never be the same again. And yet even if we do, it still won't be the same. I'm BrownWolf123, and this is the end of my latest message on Entity 303. (Yes, now I'm making this into an investigation.)
