I beated the game on hardcore sometime after my previous post, and I still think enemies dont get any more range of sight. The demons in stage 7&8 have more range by default so thats it.I guess its just here for the people that felt insulted by not being able to see a bit more.Hardcore diffuclty itself was very fun tough, and I really got to fiddle arounf more with the shockwave cannon. The range of a full charged shot is just insane.
