What could actually be more terrible than a galaxy destroying infection that has destroyed more than 2 godlike civilizations, which is also unstoppable. 343 says that halo 4 introduces a new enemy that is stronger than we anything weve seen. How come ? I cant even imagine anything more terrible then it. And, as a note, can anyone please provide me a source stating that the flood wont be in halo 4 campaign ? Its hard to believe that 343 took the most important thing in halo universe and threw it away.
