nice but up the difficulty a bit!
it was good I played the survival mode first but I just found it far too easy, enemies deont take enough off and drop too much health and too much ammo. I found that eventually I could use my smg all the time and there arnt enough enemies attacking at once. after 5 mins I let them kill me cos it was getting old :P
the aiming to kill vamps is ok but still, too easy.
I wouold also say, add a rocket launcher and add more blood and guts :P
