Thats why you drop them with about 2 - 3 bullets then run over to them and hack with the knife while they are on the ground. In fact, on easy i was quite often forced to use the knife while they were approaching me and i dropped a couple at a time without them getting a bite in.
The knife is an extremely good weapon on CV you just need to have the balls to rely on it and get in close with your enemies. Tyrant can be defeated with just the knife, once you get him on his knees for the first time with it if you just keep hacking at him he can never get back up till hes done for.
And in other news - RE 4 is very tough at the moment on PRO for me. I've no health and ive died about 4 times in battle at this certain point.Ashley is such a pain in the bum! I wish i had of chose the gangster/armor costume instead of the rpd one because then i wouldnt need to worry about her. I miss Sheva!
