Duke Nukem Forever/Headscratchers

While most fans hate the boxart, I like it. Except for one little thing. What the eff is up with Duke's left arm? Does it have 3 sections or something?
- His left hand is not visible, and is probably touching his buttock; that hand on his hip is probably a woman's, as can be inferred by the nails and structural differences.
- No, I realize the babe's hand is on his hip. But look at Duke's actual left arm. What could be called his shoulder is hanging a good few inches from the socket. Look at you left arm, then look at his. Don't you notice anything odd about Duke's?
  - Duke dislocated his shoulder fighting aliens, but he's just too damn badass to care.
  - Also: Perhaps his oversized ego causes him to thrust his chest out. That and the bandoleer (and difficulty in drawing pictures from high/low angles) causes this?
- I'm guessing it's the woman's right hand, coming over his shoulder and into his tanktop, making his left pec look too big and throwing off the proportion. Or a dumb art error, whichever works.
- Not a dumb art error, at least not of the cover artist. Look at his in-game model during the Press Conference. All your questions will be answered, he's just drawn that way.
Ok, i can accept that puny bullets don't harm the mighty dukes' health, but why does he gain ego while hiding for cover like a coward? Wouldn't it be more appropriate that he gains ego immediatly after slaying those chick stealing pig aliens like a boss? Diablo II did this by introducing life leech, so why not in an ego shooter?
- Duke gains permanent increases to his ego by doing manly things like beating bosses, winning arcade games, lifting weights, admiring himself in the mirror and urinating in a toilet. Besides, regenerating health actually made this troper more reckless, as he didn't need to worry about conserving health for later. Just outlast every alien bastard that dares attack Duke.
- Well, performing an execution on a downed enemy immediately restores your ego to full, so there's that.
- The way I interpret it is that Duke getting hit hurts his self-esteem and ego, but when he ducks into cover or avoids fire, its his equivalent of shaking off the hits to his self-esteem and psyching himself up to step back out and kick some ass.
- Still doesn't excuse the fact that one to two shots from the aliens can kill the Chuck Norris of video games.
  - Duke's ego may shield him, but it doesn't shield him that much.
- Duke doesn't gain ego while running and hiding, it just goes back to its normal size whenever he is not being stuffed with bullets. Duke is so self-absorbed and narcissistic that his spirits rise all by themselves if there is nothing to keep his ego at bay. Simply because he is the Duke.
- Again, that may be all true, but if he truly is so self-absorbed, he should have the ego the size of Europe. Unless, his small ego is telling us something else about him.
  - Well, at least he's not overcompensating...
Why does the reveal trailer call Duke "the man who disappeared without a trace"? He looks pretty famous in the actual game... Or is that another meta-joke from the line of "did you think I was gone forever"?
- I think it's a fourth wall breaking moment. After all 15 years is a hell of a long time in development for a video game.
