While fooling around with some gernades as Snake, I found that after you shield drop and pick up the gernade immediately, you can change the height of how high the gernades will fall (Only throwing it down though). Usually normally throwing it down, it will bounce a bit high, but as it descends, as soon as it hits the ground it will explode. (Decent tactic btw, for those who don't use it. It can catch opponents off gaurd, who don't expect it, either because it flew off screen, or if they're trying to pressure you while shielding) However, if your crouching (or crawling if you want to be specific) and you throw it down (With the c-stick), it will bounce lower, and as it lands, will bounce a bit, around Snake's height. It basically the same, but faster. Idk if this is already known, but I thought I'd share. It's almost usless though, but I also thought I'd share my thoughts on it. Although holding a gernade reguarly than pressing back to toss it in front of you can work, it feels rather slow and limited so yeah... ^_^
