[PS3] Metal Gear Solid 4: Guns of the Patriots

The railgun is only okay. The long charge time is what kills it. Versus anything squishy, the M82A2 is definately superior. Versus anything that isn't going to give you a chance to charge, it's almost useless. I've taken down armor with the M82A2 before, and it really wasn't that hard; Irvings should go down within a clip, gun turrets may take more. Remember, the M82 is an anti-materiel weapon, which means that its primary duty is destruction of equipment from a distance, which is the same duty as a rail gun; the difference is that in the time you get off one fully charged shot with the railgun, the M82 could probably empty its 10 round magazine twice.

I've confirmed the thing about non-lethality in the B&B fights. If you use non-lethal takedown during the main fight, there will be a statue to collect during the finishing stage (it may or may not be near where you start). If you use non-lethal takedown to finish her, you get their face as a camo option. I'd like to take this opportunity to say that non-lethal takedown during the Raven fight was quite long and annoying.

Also, I found out that you can press square during mission briefings to control the Mk. II for fun and profit. Press triangle and L2 for a better view.
