Some of the melee fatalities are extremely hard to get recorded, because they're randomized based on your position, the enemy's health, and sometimes the move you're doing. I managed to get at least one clip of every fatality in the game, though (at least I'm pretty sure). I also included a few other buggy things you can do.
