Are you implying Samus doesn't? She's been in more games than Master Chief, and in each she's singlehandedly wiped out entire species, conquered enemy strongholds, and generally saved the galaxy from various threats. Samus has the larger arsenal and the larger amount of experience.

I'm implying the MC is born to fight, and his shield technology paired with his weight gives him in some areas an advantage. I don't mean Samus is inexperianced or disadvantaged.
