Doesn't matter whether or not it's real: you bring something like that into an FPS, and everyone who isn't playing a sniper will scream 'Foul!' quicker than you can blink your eyes.hittite said:They actually make bullets that can do this. I forget what they're called, but it's a .50 Cal. round that has an explosive charge and a Tungsten core. When it hits a concrete (or brick, or block) wall, it penetrates halfway through and then blows a patch about a foot in diameter out of the backside at projectile velocities. It basically turns the enemy's cover into a grenade. There's a sniper in Iraq who got 3 kills in 1 shot with these things. (Thank you, History Channel.)
