mid rnage- ide give the edge to the the br, its more accurate and pretty strong.
Short- ide give the edge to the gnasher shotgun, it has more bb spray
grenade - plasma grenade, it can stick long range where as the locust grenade you have to run up to the person to stick them
Special weopons- the hammer of dawn, major fire power from almost any range
winner... Master Chief, He is more agile, even though the hammer could esily lower sheilds the satalite has to be there when you shoot and you cant shoot someone who is under some cover, Marcus would have lowered MC's sheilds but MC is just to tactical for him
