In MGS Peace Walker you have more than just a cardboard box. You have a Straw Box! And you can do a leap of Faith into it. You can also sneak up behind enemies and pull them into the box!
I made a real short video of Snake doing a Leap of Faith and then using the box to capture an enemy.
You'll notice Snake is wearing the Pink Camo pants to bring attention to Breast Cancer.
Hey Snake is a nice guy too.
LOL. Although that looks more like a bale than a box to me...
It's supposed to look like a bale. If itlooked like a box it would be too hard to sneak up beside someone. 
ha ha that's hilarious.
Yeah, it is pretty funny.
haha!!
That's awesome man!
That's because Peace Walker is such an awesome game! hahahah
Why does this remind me of the "trap door spider" technique?
