This game brings me the fondest memories I've ever had with an FPS. I can relate to just about everything that's being said in the video. The fantastic level design, the great soundtrack and the creepy ass crypt level.
I really do see it as one of the best shooters ever made and the tech it used was indeed second to none back then.
As annoying as the Loper can be, I still find it to have one of the greatest, most terrifying designs of any enemy that isn't a FromSoftware game.
Did I mention that the game also has one of the greatest flamethrowers of all time? The sheer range on that thing and the agonizing screams it causes. Perfection.
This game's praises can never be sung enough, it's an absolute masterpiece.
