Factual error: From the range that Snake fired his clip full of blanks at Malloy and his aide, they still would have been burned by the muzzle blasts and quite possibly deafened by the noise. They assuredly wouldn't have stood there smirking. (00:20:15)
Factual error: In the future it is possible to travel from Griffith Park to central Orange County (around 50 miles) via unpowered hang glider in only 10 or 20 minutes, according to Snake's countdown timer. This would mean the hang glider would need to be traveling somewhere between 150 and 300 miles per hour.
Factual error: When Snake has the "Bangkok Rules" showdown with the guys, they are all standing in front of him. When he fires his guns and kills them, he is firing his guns in a slightly upwards position which would have missed them.
Factual error: When Snake crashes the chopper in the final scene, it is going down nose-first, and just the nose hits the ground. The explosion area would be (approximately) 10 sq. feet and expanding outward from that spot. But the initial explosion is down the whole length of the chopper with the grass exploding into fireballs. (01:27:20)
Factual error: When Snake shoots through the tunnel in the sub and splashes into the water, the big splash comes back towards the rear of the sub, not forward of it as it would in real life. (00:21:55)
