That is all well and good, but they really needed to put feet together on the animation at 1:51. I'd rather lose a foot/feet than leave a direct shot to the jewels open.

Not what I would have guessed! Good video.

Interesting. I'd love a breakdown of the falloff on that, for future gameplay realism.

I had guessed land, just because I knew from WW2 movies and submarines that explosions underwater are Very Bad.

I would choose to jump in the pool if there was only 1 grenade on land, though. At first I didn't notice the grenade in the water and was going to go that way.

Related story: during the later years of the war, when Allied air and sea supremacy made the Bay of Biscay a deathtrap, Allied torpedo boats took up ambush positions at the entrances to U-Boot bases, particularly La Rochelle. They'd get into position at night and stay just outside of range of the coastal defence batteries. Before outgoing submarines could reach deep water, they'd be plastered with hand grenades by these speed boats.

It wouldn't be able to sink a sub, but a lucky hit might damage the periscope and it did reduce the sub's sonar abilities by massive amounts, covering the entire exit area in a blanket of noise. Not to mention the psychological effect...

Anyway, just small bits of history.

Now, about this video: that small chance to be hit by a grenade chunk is surpassed by the rather noticable chance to be hit by one of roughly 6500 steel balls within a run-of-the-mill frag grenade used over here. Doesn't make the underwater experience any better though...
