As part of their Fallout 3 coverage, TheGameReviews.com was lucky enough to sit down with Pete Hines of Bethesda Software while he showed us a walkthrough of the latest build of Fallout 3. While they were being shown the combat system, they thought this would be a good time to bring up what ESRB rating the guys are trying to hit. His response made it clear that Bethesda is not holding anything back. This will be a mature game for mature audiences.
