Killing the clown is so easy. Get like 3 golf clubs and shoot away from a distance.
It's funny to look back over what you've said nearly a year previously and I really don't know why I got stuck where I did back then; but after playing it again I realised not to save during a case. That way I'll always guarantee that I'm on time.
Still, after completing it with the real ending (helicopter arrives and it crashes) I can still say that the most annoying thing about the system is the way the healing takes like 2 to 3 seconds and you can so easily get caught out in that time by a zombie or psychopath. Not only that but you then have to try to heal again. This is the same problem with the character in general; he is too slow and the psychopaths are too fast with their simply insane aiming skills.
Oh and the SWAT teams. Way too resiliant to bullets. Two full clips of the M4? What the hell! That bit sucked almost as badly as the health system. I just couldnt stay alive whilst getting all those items; its the same old story; get shot, get up, get shot, get up, get shot, get up, get shot, dead.
