Some things you need to understand about The Evil Within's combat. Firearms will put enemies down, but only temporarily unless you take the time to finish them off. The sound of gunfire will bring other monsters in the area straight to the party. Ammo is incredibly scarce. Stealth kills are silent, but take a lot of risky maneuvering. In short, fight stealthy, quick, and smart, and if in doubt, just get the hell away and hide. And with Ruvik, hiding is the only option.
Fortunately, Sebastian’s array of throwable lures (wine bottles are most abundant in the mansion) open up the option to distract, divide and survive. His most important tactical tool, however, is his crossbow. Take, for example, the group of zombies that invade the library as I’m trying to leave. Ducking behind a desk. I fire my sole electric trap-bolt near the door, creating an electrified trip-wire, BioShock-style. That gets one of them, but there are three more. One falls to a silent arrow. The other two start patrolling aggressively, so I run back up to the top floor. I have one arrow-mounted proximity mine, so I embed it in the ladder as I hide again. After scrabbling around for a bottle, I hurl one down to get someone’s attention. My trap works. Boom. But the last mutant is now very agitated, and the last stealth kill is going to be very tricky indeed.
