+1 to this, worked MUCH better than the tip in the guide. The problem with the tip in the guide is that the weapon replacement mutator can't replace the bio rifle, so you still get whooped once the bot gets the bio rifle. With the above tip you just keep the other guy away and rely on the fact that you can get your missiles to home in on the guy.
