Thy Flesh Consumed completes DOOM, it's a final gauntlet that throws its biggest challenges at you and makes you feel at your most powerful. Levels demand you explore every niche and investigate every suspicious wall for an elevator or secret door, though never to a point of frustration as interacting with every wall in the room the game funneled you into will yield results without a need to stoop to a guide to find your way around. Your arsenal is never more complete than in Thy Flesh Consumed, you'll be keeping a constant stockpile of ammo for every single weapon and be facing droves of demons that demand that firepower. Level 7 is my favorite and least favorite level, favorite because of the points mentioned with the level acting like a massive puzzle to navigate though at the very end there is a cyberdemon in the smallest of confines that you cannot defeat without some serious patience or serious cheese. The rest of the game has sprinkles of what makes Thy Flesh Consumed so special, but it is only fully realized when you reach the fourth episode.
