that's not even a fair competition. now if you took MC out of his armor it would be a bit more even. --- build a man a fire and he will be warm for a day, but set a man on fire and he'll be warm for the rest of his life. Baka wa shinanakya naoranai.
When it comes to MC vs Shepard it depends on the weapons they are using. Mass Effect weapons are ridiculously more powerful canonically than any of the UNSC small arms. --- EMPTY [IIIII-----] FULL The WTF!?-o-meter is currently... Normal . . . [Awarded Golden Muffin of Awesomeness x2]
