Some of you friends probably never shot a gun :\ you'd all get blown away that you'd be to scared to pull the trigger again. and really like most of the logical people are saying, where the forget would you get a mini gun, a rocket launcher, grenades or all of that other stuff? How would you carry all, if not most of this stuff? Most of you are illogical idiots who strive for nothing but to be praised or have someone say "lol" to a quote of your post try to be funny or smart so just stop, because it's not working
tl;dr
YOU'RE NOT GORDON FREEMAN, YOU CANNOT CARRY 50 DIFFERENT WEAPONS AND STILL SPRINT LIKE A MOTHER forgetER.
