This game is too much for me, I get nervous before every encounter because of how fucking batshit crazy it is

Put yourself in his shoes.
You're the motherfucking DOOMSLAYER
You KILL DEMONS for breakfast
Their bones and entrails are your calling cards for your visits to any locale of note
And if they ever get you down? You get the fuck up and kick their asses for thinking they're hot shit

its natural human instinct to discover the best tool for the job and keep using it. I think I used the super shotgun for 90% of the game.
