So I'm playing Battlefield 1942 on the Midway map, and I'm at the helm of the Yamato battleship. Having just shelled the crap out of Midway island and sunk a destroyer, I'm feeling pretty satisfied when I feel the dreaded thump-thump of two torpedo impacts. Knowing I'm probably screwed, I look for the damn sub, hoping enough of the conning tower is visible enough for me to shoot him. He's submerged, but to my surprise, he's directly in front of me.
Several things from an old submarine game I used to play shoot through my mind:
"Japanese warships are perfectly willing to ram your sub."
"Just submerging won't prevent a ramming attack, as your periscope and conning tower can still be hit."
"Ramming does massive damage, more even than a depth charge attack."
I mash the W key down, pouring on as much steam as I can. Truthfully, I didn't expect it to work. Subs are ridiculously agile in that game, and he could just dive under me and finish me at his leisure. But he doesn't. He stays at periscope depth, lobbing torpedoes at me as I'm gaining speed. By now I'm driving that 80,000 ton battleship faster than I ever thought it could go. I'm nearly on him, and still he doesn't dive, and I think "Holy crap, this is going to work." I switch to the outside view, and make sure I get a good look.
The impact lifted his sub clean out of the water, crushing him against the bow of my battleship, rolls completely over, and is crushed under the Yamato's keel.
I was laughing my ass off after that, believe me.
