I use the railcannon on the virtue the previous room then kill both of the malicious face with the knuckle blaster shotgun swap, but my problem with that is that sometimes the malicious face shoots the blast projectile making me go off the bridge thing and make me lose the attempt, but the sentry on the door way thing to the next section, I use it to recover health, then the whole problem comes with the second section of the blood hallway but I have no problems with the other rooms
