Dead Space 3's Isaac Clarke isn't averse to staying in shape while combating the nightmarish forces of OH GOD WHY. All it takes is a suitable trigger for cranking up the cardio -- in this case, a friendly message of discouragement adorned upon a wall in "revulsion red" color. Off Isaac goes, soaking in a spiritually cleansing (and oxygen-depriving) spacewalk after hurling himself out the nearest airlock. A short followup jog through a hallway seemingly ripped directly from a laser tag arena keeps that pulse pumping. Check out shots from Isaac's refreshing regimen below.
