When I was playing through Rebirth today, during the part where you're fighting as Hudson in the bio-chamber room, I saw a Russian soldier propped up against a control panel in a Martyrdom-style position. When I shot him, he leapt up and charged at me... and he was invincible. I pumped him full of rounds from my HK21 and he didn't even flinch! Needless to say, he killed me. Anyone else experience this glitch?
